The Duration of Completing the Recitation of the Noble Qur'an

Question:
Finally, you ask: Did the Messenger (peace and blessings be upon him) specify a certain period for reviewing the Book of Allah?

Answer:
The Prophet (peace and blessings be upon him) did not specify a certain period for reviewing the Book of Allah, but it is required of the Muslim to increase his recitation of the Book of Allah the Exalted. 'Abdullah ibn 'Amr asked him how often he should complete a recitation of the Qur'an.
He said: "Every ten days." He said: "I am able to do more than that." He said to him: "Every seven days." He said: "I am able to do more than that." He said to him: "Every three days." He said: "I am able to do better than that." He said: "No, better than that is every three days, reciting ten parts each day, performing it at night in the tahajjud prayer; this is better." Yes. The scholars mentioned that a month should not pass without him completing a recitation of the Qur'an in it. So the upper limit for completing the recitation of the Qur'an is one month, one part each day. Yes.
