"I said: 'O Messenger of Allah! In how much time may I recite the Qur'an?' He said: 'Complete it in one month.' I said: 'I am able to do more than that.' He said: 'Then complete it in twenty (days).' I said: 'I am able to do more than that.' He said: 'Then finish it in fifteen (days).' I said: 'I am able to do more than that.' He said: 'Finish it in ten (days).' I said: 'I am able to do more than that.' He said: 'Finish it in five (days).' I said: 'I am able to do more than that.'" He ('Abdullah bin 'Amr) said: "But he did not permit me."

that the Prophet (ﷺ) said: "Recite the Qur'an in forty (days)."

"A man said 'O Messenger of Allah! Which deed is most virtuous to Allah?' He said: 'Al-Hallul-Murtahil'' He said: 'What is Al-Hallul-Murtahil?' He said: 'The one who recites from the beginning of the Qur'an to the end of it, every time he sets out (on a trip).'"

that the Prophet (ﷺ) said: "He who recites the Qur'an in less than three (days), he does not understand it."
