“I memorized the Qur’an and recited it all in one night. The Messenger of Allah (ﷺ) said: ‘I am afraid that you may live a long life and that you may get bored. Recite it over the period of a month.’ I said: ‘Let me benefit from my strength in my youth.’ He said: ‘Recite it in ten days.’ I said: ‘Let me benefit from my strength and my youth.’ He said: ‘Recite it in seven days.’ I said: ‘Let me benefit from my strength and my youth,’ but he refused (to alter it any further).”

← Previous Hadith “We came to the Messenger of Allah (ﷺ) in the delegation of Thaqif. The allies of Quraish stayed at the house of Mughirah bin Shu’bah, and the Messenger of Allah (ﷺ) camped Bani Malik in a tent belonging to him. He used to come to us every night after the ‘Isha’ and speak to us standing on his two feet, until he started to shift his weight from one foot to the other. Most of what he told us was what he had suffered from his people, the Quraish. He said: ‘(The two sides) were not equal. We were weak and oppressed and humiliated, and when we went out to Al-Madinah, the outcome of the battles between us varied; sometimes we would defeat them and sometimes they would defeat us.’ One night he was later than he usually was, and I said: ‘O Messenger of Allah, you have come to us late tonight.’ He said: ‘It occurred to me that I had not read my daily portion of Qur’an and I did not want to come out until I had completed it.’” Aws said: “I asked the Companions of the Messenger of Allah (ﷺ): ‘How did you used to divide up the Qur’an?’ They said: ‘A third, a fifth, a seventh, a ninth, an eleventh, a thirteenth, and Hizbul-Mufassal.’”
