from 'Uthman bin 'Affan that the Messenger of Allah (ﷺ) said: "The best of you is he who learns the Quran and teaches it." Abu 'Abdur-Rahman said: "So that is why I sit at this seat of mine." And he taught the Quran during the time of 'Uthman until Al-Hajjaj bin Yusuf came. (Sahih)
Jami` at-Tirmidhi Book 45, Hadith 33
← Previous Hadith "I passed by the Masjid when the people were absorbed in story-telling. So I entered upon 'Ali and said: 'O Commander of the believers! Do you not see the people are becoming engrossed in story-telling?' He said: 'They have been consumed with it?' I said: "Yes.' He said: 'As for me, I heard the Messenger of Allah (ﷺ) saying: "Indeed there comes a Fitnah" So I said: "What is the way out from it O Messenger of Allah?" He said: "Allah's book. In it is news for what happened before you, and information about what comes after you, and judgement for what happens between you. It is the Criterion (between right and wrong) without jest. Whoever among the oppressive abandons it, Allah crushes him, and whoever seeks guidance from other than it, then Allah leaves him to stray. It is the firm rope of Allah, it is the wise remembrance, it is the straight path, and it is the one that the desires can not distort, nor can the tongues twist it, nor can the scholars ever have enough of it, and it shall not become dull from reciting it much, and the amazement of it does not diminish. It is the one that when the Jinns hear it, they did not hesitate to say about it: 'Verily, we have heard a wonderful Recitation (this Quran)! 'It guides to the Right Path, and we have believed therein.' Whoever speaks according to it then he has said the truth, and whoever acts according to it he is rewarded, and whoever judges by it he has judged justly, and whoever invites to it then he guides to the straight path." Take this O A'war!'."
