It was narrated that ‘Abdullah bin ‘Amr said:“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).”
