Narrated Abdullah ibn Amr ibn al-As: Yazid ibn Abdullah said that Abdullah ibn Amr asked the Prophet صلی اللہ علیہ وسلم : 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 صلی اللہ علیہ وسلم said: He who finishes the recitation of the Quran in less than three days does not understand it.
