Narrated `Abdullah bin `Amr: Allah's Apostle said to me, "Recite the whole Qur'an in one month's time." I said, "But I have power (to do more than that)." Allah's Apostle said, "Then finish the recitation of the Qur'an in seven days, and do not finish it in less than this period."

Narrated `Abdullah bin `Amr bin Al-`As: Allah's Apostle told me, "The most beloved prayer to Allah is that of David and the most beloved fasts to Allah are those of David. He used to sleep for half of the night and then pray for one third of the night and again sleep for its sixth part and used to fast on alternate days."

Narrated `Abdullah bin `Amr: The Prophet asked me, "How long does it take you to finish the recitation of the whole Qur'an?"
