Abu Dawud

Narrated Abdullah bin Amr: The Prophet ﷺ as saying to him: Complete the recitation of the Qu'ran in one month. He said: I have more strength. He (the Prophet) said: Complete the recitation in twenty days. He again said: I have more energy. He said: Recite in fifteen days. He again said: I have more energy. He said: Recite in ten days. He again said: I have more energy. He said: Recite in seven days, do not add to it. Abu Dawud said: The tradition narrated by Muslim is more perfect.

Narrated Abdullah bin Amr: The Messenger of Allah ﷺ said to me: Keep fast for three days of month, and finish the recitation of the Quran in one month. I and he differed among ourselves on period of time. He said: Fast one day and give it up other day. The narrator Ata said: The people differed from my father (in narrating the period of time). Some narrated seven days and others five.

Narrated Abdullah ibn Amr ibn al-As: Yazid ibn Abdullah said that Abdullah ibn Amr asked the Prophet ﷺ: In how many days should I complete the recitation of the whole Quran, Messenger of Allah? He replied: In one month. He said: I am more energetic to complete it in a period less than this. He kept on repeating these words and lessening the period until he said: Complete its recitation in seven days. He again said: I am more energetic to complete it in a period less than this. The Prophet ﷺ said: He who finishes the recitation of the Quran in less than three days does not understand it.

Khaithamah reported that Abdullah bin Amr said: The Messenger of Allah ﷺ said to me: Recite the Quran in one month. I said: I have (more) energy. He said: Recite it in three days Abu Ali said: I heard Abu Dawud say: I heard Ahmad bin Hanbal say: The narrator 'Isa bin Shadhan is a sane person.
