The 365 · Verses · Day 177 · Knowledge
The firmly rooted believe. The unrooted argue. The same revelation reaches both; only one drinks.
Qur'an 4:162
لَّـٰكِنِ ٱلرَّٰسِخُونَ فِى ٱلْعِلْمِ مِنْهُمْ وَٱلْمُؤْمِنُونَ يُؤْمِنُونَ بِمَآ أُنزِلَ إِلَيْكَ وَمَآ أُنزِلَ مِن قَبْلِكَ ۚ وَٱلْمُقِيمِينَ ٱلصَّلَوٰةَ ۚ وَٱلْمُؤْتُونَ ٱلزَّكَوٰةَ وَٱلْمُؤْمِنُونَ بِٱللَّهِ وَٱلْيَوْمِ ٱلْـَٔاخِرِ أُو۟لَـٰٓئِكَ سَنُؤْتِيهِمْ أَجْرًا عَظِيمًا
“But those of them who are firmly grounded in knowledge and have faith do believe in what has been revealed to you [Muhammad] and others before you. We shall give a great reward to those who perform the prayers, pay the prescribed alms, and believe in God and the Last Day. (Abdel Haleem)”
Svenska: Men de av dem vars kunskap är fast och djupt rotad tror med de troende på det som har uppenbarats för dig och på det som uppenbarades före din tid, och de som regelbundet förrättar bönen och hjälper de behövande och tror på Gud och den Yttersta dagen, alla dessa skall Vi ge en rik belöning. (Knut Bernström)
The story
Allah is addressing the People of the Book in this passage. The majority rejected the Qurʾan; a small number recognized its truth and embraced it. The verse names them: those firmly rooted in knowledge (al-rāsikhūna fī al-ʿilm) among them, and the believers, believe in what was sent to you (Muḥammad ﷺ) and what was sent before. Knowledge, when it is deep enough, recognizes the truth across revelations. Knowledge, when it is shallow, gets caught in tribal allegiances.
In the language
Al-rāsikhūna (الراسخون) is from r-s-kh, to be firmly planted, deeply rooted. The image is of a tree whose roots go so deep that no wind can uproot it. The firmly rooted in knowledge are those whose knowledge has gone past the surface into the foundational principles, so they cannot be swayed by the surface-level arguments. Muʾminūn (مؤمنون) is the active participle of īmān; they are the ones in the state of belief, not just those who once believed.
Why this verse
Allah names the discriminator: depth of knowledge. The deeply knowledgeable among the People of the Book recognized the Prophet ﷺ; the surface-knowledgeable rejected him. The verse explicitly attaches faith to knowledge-depth and pairs it with the four structural acts (prayer, zakāh, belief in Allah, belief in the Last Day). The reward Allah names is ajran ʿăzīman, a great reward, the same phrase He uses for the highest stations of believers.
Bring it into today
Depth of knowledge protects against the storms of skepticism. The shallow Muslim is uprooted by the first Twitter argument; the firmly rooted Muslim, who has gone deeper into the principles, weathers it. Build depth. Read more than headlines. Study tafsīr, not just translation. Learn the Sunnah, not just the slogans. The roots that go deep are the roots that hold when storms come.
A reflection to carry
Allah names the discriminator between those of the People of the Book who recognized the Prophet ﷺ and those who rejected him. The discriminator is depth of knowledge. He said: 'But those firmly rooted in knowledge among them, and the believers, believe in what has been revealed to you and what was revealed before' (4:162). The Arabic word is al-rāsikhūn, from r-s-kh, to be firmly planted, deeply rooted, like a tree whose roots go past the surface into the bedrock. The deeply rooted scholars among the Jews and Christians of seventh-century Arabia recognized the Prophet ﷺ because their knowledge had gone past the tribal allegiances of their communities into the foundational principles of revelation, where the consistency of Allah's message across prophets was visible. The shallow scholars, whose roots only went as deep as the surface convictions of their communities, could not see past the immediate disruption the Prophet ﷺ represented. The same revelation reached both groups; only the deeply rooted drank. Today, depth of knowledge is the protection against every wave of skepticism that washes over the umma. The shallow Muslim is uprooted by the first Twitter argument; the firmly rooted Muslim, who has gone deeper into tafsīr, the seerah, the foundational principles, the discipline of uṣūl al-fiqh, the spiritual core of the salaf, weathers it. Build depth.
Read the longer reflection
Sit with the metaphor Allah chose. He called them al-rāsikhūna fī al-ʿilm, the firmly rooted in knowledge. The Arabic verb r-s-kh is used in Classical Arabic for a tree whose roots have gone so deep into the earth that no storm can shake it. The shallow-rooted tree may look the same as the deep-rooted tree on a calm day. But when the wind comes, the shallow tree falls and the deep tree stands. The metaphor is the structural Islamic teaching about knowledge. Two believers may seem identical on Friday in the masjid, both wearing white, both praying. One has built his understanding on quick lectures, social media clips, and surface-level argumentation. The other has gone deeper: tafsīr, hadith methodology, uṣūl al-fiqh, the spiritual literature of the salaf, the linguistic foundations of the Qurʾan's Arabic, the lives of the Companions. On a calm day, both look the same. On a stormy day, the first uproots and the second holds. The storm comes in many forms. The orientalist's argument. The atheist's video. The modernist scholar's revisionism. The cultural pressure of secularism. The personal crisis that demands an explanation for suffering. The intellectual encounter with a polished critique of Islamic teachings. The shallow Muslim, when these storms arrive, has nothing structural to hold. His roots only went as deep as the surface convictions he absorbed. When the wind blows hard enough, he is uprooted. He becomes the Muslim who 'used to believe' or the one who 'is going through a faith crisis' or the one who 'no longer identifies that way'. The firmly rooted, on the other hand, weathers the storm. His knowledge has gone past the surface to the foundational principles. He has read enough tafsīr to know that the Qurʾan has multiple layers; he has studied enough hadith methodology to know how the Sunnah was preserved with rigor; he has internalized enough uṣūl al-fiqh to know that scholarly disagreement does not equal contradiction; he has spent enough time in the spiritual literature to know that the heart's testimony is itself a form of knowledge. When the storm comes, his roots hold. He may bend, he may question, he may explore, but he does not fall. Allah, in this verse, names this depth as the discriminator. Of the People of the Book in the Prophet's ﷺ time, those firmly rooted in knowledge recognized the Qurʾan's continuity with the previous revelations and embraced Islam: ʿAbdullāh ibn Salām, the rabbi of Madinah; Saʿd ibn Ubādah, Tamīm al-Dārī, Salmān al-Fārisī (who had been a Christian seeker), and many others. The shallow scholars of those same communities, whose knowledge had only gone as deep as their tribal allegiances, could not see past the disruption. Knowledge depth, when sincere, leads to recognition; knowledge surface, when defensive, leads to rejection. And then Allah pairs this depth-knowledge with the four structural acts: belief in what was revealed to you and what was revealed before; establishing the prayer; paying zakāh; belief in Allah and the Last Day. Knowledge that does not translate into these acts is not the knowledge Allah praises. The firmly rooted scholar prays. The firmly rooted scholar gives. The firmly rooted scholar believes structurally in the Day. And the reward is named: ajran ʿăzīman, a great reward, the same phrase Allah uses for the elite of the believers. The cure for shallow knowledge is depth. Pick one area of Islamic knowledge you have only encountered at the surface, and go deeper. Read a tafsīr of one sūrah in full. Study the seerah from a serious source like Mubarakpuri or al-Ghazzālī. Take a course in hadith methodology. Read one classical text in uṣūl al-fiqh, even a beginner-level one. Over a year, your roots will go deeper. When the storms come, you will stand. Pray today: Allāhumma rsikhnī fī ʿilmika, wa-ajʿalnī mim man yathbutu ʿinda ʿăṣifat al-fitan. O Allah, root me firmly in Your knowledge, and make me of those who stand firm when the storms of trials come. The wind is rising in many directions; depth of root is the protection.
