Virtues of the Qur'an

Bukhari :: Book 6 :: Volume 61 :: Hadith 574

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."
