The trench held. Ten thousand men stood on the far side of a ditch they could not cross, and so they did the only thing left to them: they sat down to wait the believers out. But a siege is not won at its walls alone. It is won, or lost, in the hearts of the people trapped inside, and on this third day with the Battle of the Trench, Dr. Yasir Qadhi walks you into the longest night Madinah ever knew.
The danger this time does not ride up on a horse. It slips in through a door at the back of the city, it whispers in the gatherings of the faithful, and it bleeds slowly from the arm of a beloved man. This is the siege from within.
The whisper at the back door
Inside the city walls there was still one tribe that had not joined the fight: Banu Qurayza, bound to the Prophet ﷺ by a written treaty, confirmed more than once, the last time only months before. They were the final piece, and the enemy knew it. So a man came for them in the dark.
His name was Huyayy ibn Akhtab, a chieftain of the Jewish tribes already exiled from Madinah, and the father of the woman who would one day be the Prophet's ﷺ wife, Safiyyah. He made his way back into the city he knew well and knocked at the fortress of Ka'b ibn Asad, the chief of Banu Qurayza. Ka'b would not open. You bring bad luck, he called through the door, you are an evil omen, go away. Huyayy kept knocking. He had a treaty with Muhammad ﷺ, Ka'b said, and would not break it, for he had only ever seen truthfulness and faithfulness from him.
So Huyayy changed his weapon. You only keep the door shut, he taunted, because you are too stingy to share your food with me, leaving an old friend out in the night. The insult stung the door open. And the moment it did, the real assault began: I have brought you oceans of men, Huyayy told him, the chiefs of every tribe with their armies, and they have sworn not to leave until Muhammad ﷺ and his companions are wiped out. How could a plan this large possibly fail?
A man who sealed his own verdict
Ka'b's instinct was screaming at him. He answered Huyayy with an Arab proverb sharp as a blade: you are a cloud that promises rain and gives only thunder and lightning. You make these fat promises, he was saying, and the end of it will be ruin. But Huyayy would not stop. All night he pressed, and pressed, and pressed.
Then he played his last card. To prove how certain he was, Huyayy pledged that if the great armies left without finishing the job, he himself would stay behind and share Banu Qurayza's fate, whatever it turned out to be. Here Dr. Yasir Qadhi makes you pause, because that is the line that decides everything. A man does not stake his own life on a plan unless he is sure it cannot fail. And that certainty was exactly the thing that finally broke Ka'b's resistance.
By morning, Huyayy had won. The treaty was a physical document, and Ka'b tore it up with his own hands. This is the detail to hold onto, the Sheikh insists, because people look at the punishment that will eventually come to this tribe and forget the road that led to it. They had given their word, in writing, again and again. They tore it up at the single worst moment for the people they had sworn peace with, with an enemy army of ten thousand at the gates.
Send me the wise ones
The first hint that something was wrong came from Zubayr ibn al-Awwam, watching the perimeter. He could see Huyayy slipping toward the fortress; he could not hear the words. So he brought back a suspicion, not a fact, and for it the Prophet ﷺ gave him a title that became his forever: every prophet has a disciple, and you are mine.
But suspicion was not enough to act on. The Prophet ﷺ chose his envoys with care, the senior companions of the Ansar who had the oldest and best ties to this tribe: Sa'd ibn Mu'adh, the leader of the Aws, and Sa'd ibn Ubadah, the leader of the Khazraj, with a small delegation of their elders. Go and confirm it, he told them. And if it is true, do not say so out loud, only hint it to me. He was not behind palace walls with secretaries and guards like an emperor; he was out among his people on the front line, where every word he spoke could be heard by everyone. If they have turned traitor, signal it quietly, he said, do not spread fear among the people and weaken them. But if they are still faithful, then shout it for all to hear.
The delegation found Banu Qurayza at their worst: vulgar, mocking, foul. We know no Muhammad, they sneered, and we have no treaty with him, this from people who had torn that very treaty apart days before. Sa'd ibn Ubadah, known for his temper, flared and traded curses with them, until Sa'd ibn Mu'adh, the calmer of the two, held him back: my brother, what is between us and them now is far greater than insults. Cursing will not help us. They rode back and gave the Prophet ﷺ their coded signal, the names of two tribes who had once feigned faith only to massacre Muslims who trusted them. He understood at once.
Good news, on the worst of nights
إِذْ جَاءُوكُم مِّن فَوْقِكُمْ وَمِنْ أَسْفَلَ مِنكُمْ وَإِذْ زَاغَتِ الْأَبْصَارُ وَبَلَغَتِ الْقُلُوبُ الْحَنَاجِرَ وَتَظُنُّونَ بِاللَّهِ الظُّنُونَا
“[Remember] when they came at you from above you and from below you, and when eyes shifted [in fear], and hearts reached the throats, and you assumed about Allah [various] assumptions.”
Surah al-Ahzab 33:10 Read 33:10 with tafsir
هُنَالِكَ ابْتُلِيَ الْمُؤْمِنُونَ وَزُلْزِلُوا زِلْزَالًا شَدِيدًا
“There the believers were tested and shaken with a severe shaking.”
Surah al-Ahzab 33:11 Read 33:11 with tafsir
When the news of the betrayal reached the Prophet ﷺ, he said the last thing anyone expected. Glad tidings, he said. Good news. He alone, with a trust in Allah no other heart could hold, read the worst possible report and saw something good buried inside it: this was the final tribe in Madinah still outside Islam, and their breaking of the treaty meant that, in time, the whole of the city would be made firm. Who else could take news like that and find in it a reason to rejoice?
For everyone else, this was the worst night of the entire siege. When word of the treachery spread, the fear was unlike anything before it: now there were enemies above the city and enemies below it, an army outside the trench and a tribe of warriors with their own fortress inside the walls, between the believers and their undefended women and children. This is the night Allah Himself describes, when even the strongest of the companions felt their minds run wild and their hearts climb into their throats.
When the mask came off
وَإِذْ يَقُولُ الْمُنَافِقُونَ وَالَّذِينَ فِي قُلُوبِهِم مَّرَضٌ مَّا وَعَدَنَا اللَّهُ وَرَسُولُهُ إِلَّا غُرُورًا
“And [remember] when the hypocrites and those in whose hearts is disease said, "Allah and His Messenger did not promise us except delusion,"”
Surah al-Ahzab 33:12 Read 33:12 with tafsir
لَّا تَجْعَلُوا دُعَاءَ الرَّسُولِ بَيْنَكُمْ كَدُعَاءِ بَعْضِكُم بَعْضًا ۚ قَدْ يَعْلَمُ اللَّهُ الَّذِينَ يَتَسَلَّلُونَ مِنكُمْ لِوَاذًا ۚ فَلْيَحْذَرِ الَّذِينَ يُخَالِفُونَ عَنْ أَمْرِهِ أَن تُصِيبَهُمْ فِتْنَةٌ أَوْ يُصِيبَهُمْ عَذَابٌ أَلِيمٌ
“Do not make [your] calling of the Messenger among yourselves as the call of one of you to another. Already Allah knows those of you who slip away, concealed by others. So let those beware who dissent from his [i.e., the Prophet's] order, lest fitnah strike them or a painful punishment.”
Surah an-Nur 24:63 Read 24:63 with tafsir
Pressure separates people, and this night separated the believers from the hypocrites once and for all. The munafiqun came asking for permission to slip home, with the excuse that their houses were undefended and their families exposed. Allah names the excuse for what it was: their homes were not exposed, they simply wanted to flee.
One of them said it out loud in the gathering, dripping with contempt. Here was Muhammad, he scoffed, naming him flatly, the way you call any man and never the way a believer should address the Messenger ﷺ. Here was Muhammad promising us the treasures of Kisra and Qaysar, the Persian and the Roman emperors, and now we are too terrified to even step out to relieve ourselves. It was crude, it was cruel, and it was spoken to the noblest of creation in his hardest hour.
Now stand at the far end of that sentence. Six or seven years later, not even a decade, not even a generation, the Muslims were eating from the dinner plates of the Persian emperor, exactly as the Prophet ﷺ had promised. The hypocrite could not see past his own fear; the believer simply had to wait, and trust, and watch the promise come true.
Why Islam keeps its silence
There is a quiet instruction buried in that night that Dr. Yasir Qadhi will not let you walk past. The treachery had happened, it was real, and still the Prophet ﷺ said: keep it low, do not go telling everyone. Not because it was false, but because spreading even true evil corrodes the people who hear it.
This is one of the most pressing lessons of the whole siege. Islam does not sensationalize, does not broadcast every gruesome detail, every scandal, every salacious rumor. Madinah was an ideal society, and still it was not a utopia; even there, wrong things happened. But the way of the Prophet ﷺ was to keep them hidden, not to parade them, because a heart that is fed a constant diet of crime and cruelty grows numb to it. Allah says the same elsewhere: why did you not take the matter to those in authority instead of spreading it? The instinct to expose, to analyze, to make everything public, is not the instinct Islam trains in you. It trains you to cover, to protect, and to keep society's heart soft.
The smallest count of all
Out at the trench, a few skirmishes broke out. One small band of horsemen, five of them, found a narrow point with no one guarding the far side and flung their horses across. At their head was Amr ibn Abd Wud, an elder of the Quraysh famous for his ferocity, who had killed at Badr and now rode wearing the red turban that was his open boast of death: come and fight me, and I will kill you.
He called for a duel. A young man rose, in his mid twenties, no match on paper for a warrior with decades of battle behind him: Ali ibn Abi Talib. The Prophet ﷺ held him back, once, twice, telling him to let an elder go. But no elder rose. When Amr called a third time and Ali asked a third time, the Prophet ﷺ saw his zeal and let him go. Amr knew the boy, had watched him grow up, and waved him away: go back, child, send me a man, I have no wish to kill you. And Ali answered: but I have a wish to kill you. The dust the two horses raised swallowed them whole, and the only word that came back out of it was a single Allahu Akbar. Ali had won, with a blow so swift it ended the fight before it began. Nearby, Zubayr struck another of the attackers, Nawfal, with such force that the body split in two; when they marveled at his sword, he answered: it is not the sword, it is the arm.
When the enemy offered to buy back Nawfal's corpse, the Prophet ﷺ refused their money: the body is yours to bury, but we have no need of the price of corpses, come and take it. He gave even his enemies the dignity of burial, and took nothing for it. And here is the wonder the Sheikh asks you to sit with: this was the largest army ever gathered against the Prophet ﷺ, ten thousand strong, and yet it produced one of the very smallest counts of the dead in all the major battles, a few of the enemy, six or seven of the Muslims, most of those from arrows. The casualties were so few you could nearly count them on one hand. When Allah fights on your side, even the numbers bow.
The arrow that found Sa'd
The true tragedy of the Trench was not a duel. It was a single arrow. Sa'd ibn Mu'adh, chieftain of the Aws and one of the envoys to Banu Qurayza, had come to his mother's tent to say farewell before taking his place on the line. His mother, who loved him fiercely, told him not to linger: hurry, my son, you are late. As he left, she worried at how little armor he wore, his chest covered but his arms bare, for he could not afford more. An arrow struck him in the exposed upper part of his arm, exactly where she had feared, and drove deep. The man who shot it shouted his name in triumph: take that from me. Sa'd answered only with a prayer against him.
Sa'd ibn Mu'adh was no ordinary man. He had accepted Islam early at the hands of Musab ibn Umayr, and when he did, his love among his people was so great that an entire tribe embraced the faith out of love for him. It was Sa'd who, on the eve of Badr, had stood and spoken the words that steadied the whole army: go wherever Allah has shown you, and we are with you, we will never say to you what others said to Musa, you and your Lord go and fight while we sit here. The Prophet ﷺ carried him in his heart so deeply that years after Sa'd was gone, gazing at the finest robe a foreign king had ever sent him, dazzling the companions, he would say only: the handkerchief of Sa'd in Paradise is finer than this.
Now Sa'd lay bleeding in a tent the companions raised for him, and the Prophet ﷺ visited him in it. And on what he did not yet know was the edge of death, Sa'd made his du'a: O Allah, if any fighting remains against the Quraysh, then let me live to fight them, for there is no people more hateful to me than those who hurt Your Messenger ﷺ. But if You have ended the war between us, then take me as a martyr, and do not let me die until You have cooled my eyes with what becomes of Banu Qurayza. Hold that prayer. Every word of it would be answered.
The prayer they were robbed of
On one terrible day the fighting and the arrows grew so relentless that the Muslims could not stop to pray. They did not refuse the prayer; they were so consumed by survival that the thought of it slipped past them entirely until its time had gone. This is one of only two times in the Prophet's ﷺ entire life that a prayer was missed, and both were beyond his control.
When it was done, the depth of his anger told you everything about where his heart lived. They kept us from the middle prayer, he said, until the sun had set, may Allah fill their houses and their graves with fire. Read that again. He was on a battlefield, an army of ten thousand at his gates, his own life and his city in danger, and the thing that made him burn with rage was that he had been kept from his prayer. Then he made wudu and prayed it after sunset, in its proper order. If this was his fury at missing one prayer under siege, the Sheikh asks, what then of the one whose business, whose entertainment, whose comfort robs him of his prayers in perfect safety?
The stranger Allah sent
Around the twentieth day, with the siege grinding on and the believers worn thin, a man walked out of the dark and into the Muslim camp. His name was Nu'aym ibn Mas'ud, of the tribe of Ghatafan, one of the besieging armies. I have accepted Islam, he said, and no one among my people knows it. Tell me what to do. Out of nowhere, Allah had sent the one man who could undo the whole alliance from the inside: a secret Muslim, trusted by the Quraysh, trusted by Banu Qurayza, and a member of Ghatafan, all at once.
You are only one man, the Prophet ﷺ told him, so go and do whatever you can to protect us, for war is deceit. Nu'aym took that as his license, and the genius of his plan was that he never told a single lie that broke a trust; he only sowed doubt. To Banu Qurayza he said, as an old friend: do not fight alongside the Quraysh until they hand you hostages from their own nobles, for if the siege drags and they tire, they will simply go home, and you will be left here alone to face the consequences. Sound advice, and they took it. Then he went to the Quraysh and warned them, in confidence: Banu Qurayza regret breaking their treaty, and they have secretly offered the Muslims to hand over your nobles to be executed as a peace offering, so if they ask you for hostages, send them no one.
Within hours the seed had taken root. The Quraysh sent to Banu Qurayza, and Banu Qurayza sent back demanding hostages first, and neither side would move, each now certain the other was a trap. The alliance of ten thousand, unbroken at the trench, had begun to crack from within over a single planted doubt. Dr. Yasir Qadhi leaves you here, on the night the tide began to turn, and the rest, the wind, the lifting of the siege, and the verdict that Sa'd ibn Mu'adh prayed to live and see, waits for the days to come.
