What did the Prophet Muhammad (peace be upon him) instruct Abdullah bin `Amr to do regarding the recitation of the Qur'an?
 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."
