It is narrated from the Mother of the Believers, Sayyidah Aishah (may Allah be pleased with her), that she said: The Messenger of Allah (peace and blessings be upon him) used to fast (voluntary fasts) so much that we would say he would not stop fasting now, and when he stopped fasting we would say he would not fast now. And he (peace and blessings be upon him) used to recite Surah Bani Isra'il and Surah al-Zumar every night.

It is narrated from Sayyiduna al-Zubayr bin al-Awwam (may Allah be pleased with him) that when this verse was revealed to the Messenger of Allah (peace and blessings be upon him): "Indeed, you will die, and indeed, they will die. Then indeed, on the Day of Resurrection, you will dispute before your Lord" [Surah al-Zumar: 30-31] , I said: "Will the dealings that took place between us in the world be brought up again, along with the particular sins?" He (peace and blessings be upon him) said: "Yes, they will certainly be brought up again before you, until every rightful claimant is given his right." Sayyiduna al-Zubayr (may Allah be pleased with him) said: "By Allah, then the matter is very severe."

It is narrated from Sayyiduna Abdullah bin al-Zubayr (may Allah be pleased with him) that when this verse was revealed. Then the narrator mentioned the same previous hadith, but he did not mention Sayyiduna al-Zubayr (may Allah be pleased with him) (his father) in its chain. This hadith is sahih (authentic) on the condition of Imam Muslim, but the two Shaykhs (Bukhari and Muslim) did not record it.

It is narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) that he said: We used to say that there is no repentance for one who has fallen into trial (and abandoned the faith), and that Allah will not accept anything from him. But when the Messenger of Allah (peace and blessings be upon him) came to Madinah, this verse was revealed concerning them: "Say: O My servants who have transgressed against themselves, do not despair of the mercy of Allah. Indeed, Allah forgives all sins. Indeed, it is He who is the Most Forgiving, the Most Merciful" [Surah al-Zumar: 53] , and the verses after it as well. Sayyiduna Umar (may Allah be pleased with him) said: I wrote these verses, mounted my camel and went around Madinah (reciting them to the people). Then the Messenger of Allah (peace and blessings be upon him) remained in Makkah, waiting for Allah Almighty to grant him and his Muhajir companions permission to emigrate, while Sayyiduna Abu Bakr (may Allah be pleased with him) remained waiting for permission to be given to the Messenger of Allah (peace and blessings be upon him) so that he could set out with him. This hadith is sahih (authentic) on the condition of Imam Muslim, but the two Shaykhs (Bukhari and Muslim) did not record it.
