Mu'adh ibn Jabal asked the Prophet ﷺ for a deed that would lead him to Paradise and keep him from the Fire. The Prophet ﷺ called it a great question, then unfolded a whole map: worship Allah alone, keep the pillars, then the gates of good, fasting is a shield, charity extinguishes sin, and the prayer of the depths of night.
Then he gathered it all under one warning. He took hold of his own tongue and said: restrain this. For is there anything that throws people on their faces into the Fire more than the harvest of their tongues?
Where this hadith comes from
It is narrated by Mu'adh ibn Jabal (ra), one of the young Companions the Prophet ﷺ praised for his deep knowledge, recorded by at-Tirmidhi (2616), who graded it hasan sahih (good and authentic). It is also found in the Musnad of Imam Ahmad and the Sunan collections of an-Nasa'i and Ibn Majah, so it reaches us through several routes.
The setting is preserved in the report itself: Mu'adh was walking near the Prophet ﷺ one morning on a journey when he asked his question. What looks like a single saying is really a guided conversation, the Prophet ﷺ answering a sincere seeker one layer at a time, from the foundation up to the warning about the tongue.
The key words
What it means, line by line
The Prophet ﷺ calls the question great, then begins with the foundation: worship Allah alone with nothing beside Him, then the prayer, zakah, fasting, and pilgrimage. On that he opens the 'gates of good', fasting that shields, charity that puts out sin as water puts out fire, and the night prayer, then he structures the whole religion as a body: Islam its head, prayer its pillar, and striving its highest peak.
He recites this verse for the people of the night prayer, whose sides leave their beds to call on their Lord between fear and hope. Then comes the climax: he takes hold of his own tongue and says, restrain this, warning Mu'adh that nothing casts people into the Fire on their faces more than what their tongues reap. The smallest organ holds the rein over everything built above it.
The foundation, then the heights
The Prophet ﷺ began where everything begins: worship Allah alone, associate nothing with Him, and keep the prayer, the zakah, the fast, and the pilgrimage. This is the foundation, the same five we met in hadith 3. Paradise is built on it.
Then he opened a door: shall I not guide you to the gates of good? And he named them, fasting as a shield against sin, charity that puts out wrongdoing as water puts out fire, and the prayer of a person in the deep of the night, when the world sleeps and the soul rises to its Lord:
The head, the pillar, the peak
Then the Prophet ﷺ structured the whole religion in an image: shall I not tell you of the head of the matter, its pillar, and its highest peak? The head is Islam itself, submission to Allah. Its pillar, the thing that holds the structure up, is the prayer. And its highest peak is striving in the path of Allah.
Step by step he was showing Mu'adh that the religion is not a flat list but a living structure, with a foundation, supporting pillars, gates of extra good, and a summit. A believer can spend a lifetime climbing it.
The rein over all of it
And then the climax. When Mu'adh asked how to keep hold of all this, the Prophet ﷺ took his own tongue between his fingers and said: restrain this. Mu'adh, amazed, asked, will we really be taken to account for what we say? And the Prophet ﷺ answered that nothing casts people into the Fire on their faces more than what their tongues reap.
After all the worship and the gates of good and the lofty peak, the thing most likely to undo it is the small wet muscle in the mouth. The tongue is the rein on the whole animal; lose it, and everything you built can run off a cliff. Guard it, and you guard the lot.
Carry this with you
Build the whole structure, then guard the rein that protects it: your tongue.
Begin with the foundation.
Worship Allah alone and keep the pillars. Paradise is built on this.
Climb through the gates of good.
Fasting shields, charity extinguishes sin, and night prayer lifts the soul. There is always higher to go.
Know the structure.
Islam is the head, prayer the pillar, striving the peak. The religion is a living building, not a flat list.
Guard the tongue.
Nothing throws people into the Fire more than the harvest of their words. Hold the rein and you hold it all.
A du'a to carry
رَّبِّ ٱغْفِرْ وَٱرْحَمْ وَأَنتَ خَيْرُ ٱلرَّٰحِمِينَ
Rabbi-ghfir warham wa Anta khayru r-rahimin
My Lord, forgive and have mercy, and You are the best of the merciful. (Al-Mu'minun 23:118)
A du'a to guard the tongue
Mu'adh asked for the way to Paradise, and the Prophet ﷺ gave him a whole structure to build, foundation, gates, and summit, then warned him that the smallest organ could pull it all down.
So build with both hands: the worship, the fasting, the giving, the night prayer, the climb. And then guard the rein. Hold your tongue, and you protect everything you have raised.
O Allah, lead us to the deeds that bring us near to You and keep us from the Fire. Open for us the gates of good, raise us through them, and set a guard upon our tongues. Forgive us and have mercy on us, for You are the best of the merciful. Ameen.
