Chapter : Concerning the careful remembering of the Qur’an.

Abu Burda narrated on the authority of Abu Musa that the Messenger of Allah (may peace be upon him) had said to Abu Musa: If you were to see me, as I was listening to your recitation (of the Qur’an) yester-night (you would have felt delighted). You are in fact endowed with a sweet voice like that of David himself.
