It is narrated from Sayyiduna Abdullah bin Amr (may Allah be pleased with them both) that the Prophet (peace and blessings be upon him) said: "It will be said to the hafiz of the Qur'an on the Day of Resurrection: Recite and ascend, and recite in measured tones just as you used to recite in measured tones in the world, for your station is where your last verse ends."
