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.  

أَنَّ النَّبِيَّ ﷺ قَالَ لَهُ اقْرَإِ الْقُرْآنَ فِي شَهْرٍ قَالَ إِنِّي أَجِدُ قُوَّةً قَالَ اقْرَأْ فِي عِشْرِينَ قَالَ إِنِّي أَجِدُ قُوَّةً قَالَ اقْرَأْ فِي خَمْسَ عَشْرَةَ قَالَ إِنِّي أَجِدُ قُوَّةً قَالَ اقْرَأْ فِي عَشْرٍ قَالَ إِنِّي أَجِدُ قُوَّةً قَالَ اقْرَأْ فِي سَبْعٍ وَلاَ تَزِيدَنَّ عَلَى ذَلِكَ  

The Messenger of Allah ﷺ said to me: Keep fast for three days of month, and finish the recitation of the Qur'an 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.  

لِي رَسُولُ اللَّهِ ﷺ صُمْ مِنْ كُلِّ شَهْرٍ ثَلاَثَةَ أَيَّامٍ وَاقْرَإِ الْقُرْآنَ فِي شَهْرٍ فَنَاقَصَنِي وَنَاقَصْتُهُ فَقَالَ صُمْ يَوْمًا وَأَفْطِرْ يَوْمًا قَالَ عَطَاءٌ وَاخْتَلَفْنَا عَنْ أَبِي فَقَالَ بَعْضُنَا سَبْعَةَ أَيَّامٍ وَقَالَ بَعْضُنَا خَمْسًا  

Yazid ibn Abdullah said that Abdullah ibn Amr asked the Prophet ﷺ: In how many days should I complete the recitation of the whole Qur'an, 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 Qur'an in less than three days does not understand it.  

أَنَّهُ قَالَ يَا رَسُولَ اللَّهِ فِي كَمْ أَقْرَأُ الْقُرْآنَ قَالَ فِي شَهْرٍ قَالَ إِنِّي أَقْوَى مِنْ ذَلِكَ يُرَدِّدُ الْكَلاَمَ أَبُو مُوسَى وَتَنَاقَصَهُ حَتَّى قَالَ اقْرَأْهُ فِي سَبْعٍ قَالَ إِنِّي أَقْوَى مِنْ ذَلِكَ قَالَ لاَ يَفْقَهُ مَنْ قَرَأَهُ فِي أَقَلَّ مِنْ ثَلاَثٍ  

The Messenger of Allah ﷺ said to me: Recite the Qur'an 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 b. Hanbal say: The narrator 'Isa b. Shadhan is a sane person.  

لِي رَسُولُ اللَّهِ ﷺ اقْرَإِ الْقُرْآنَ فِي شَهْرٍ قَالَ إِنَّ بِي قُوَّةً قَالَ اقْرَأْهُ فِي ثَلاَثٍ قَالَ أَبُو عَلِيٍّ سَمِعْتُ أَبَا دَاوُدَ يَقُولُ سَمِعْتُ أَحْمَدَ يَعْنِي ابْنَ حَنْبَلٍ يَقُولُ عِيسَى بْنُ شَاذَانَ كَيِّسٌ
