Virtues of the Qur'an -12

narrated 'abdullah bin 'amr (radi-allahu 'anhu):

allah's apostle (sallallahu 'alaihi wa sallam) 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 (sallallahu 'alaihi wa sallam) said, "then finish the recitation of the qur'an in seven days, and do not finish it in less than this period."
