Abu Hurairah Radiyallahu 'anhu narrates that Rasullullah Sallallahu 'alaihi wasallam said: Learn the Qur'an and then recite it. For indeed, the likeness of the one who learnt the Qur'an, recited it, and (then) stood up reciting it (in Tahajjud), is like a bag filled with Musk, whose fragrance spreads all over the place. The likeness of the one who learnt the Qur'an and slept at night and did not recite (in Tahajjud Salat), while he had the Qur'an within him, is like a bag of Musk whose mouth was sealed. (Tirmidhi: 2876)
