It is narrated from Abu Sa'id al-Khudri that Rasulullah s.a.w. said: "Allah says:
من شغله قراءة القرآن عن مسألتي و ذكري السائلين
"Whosoever is preoccupied by the Qur'an and dhikr of asking me, then I will give it the ultimate thing among what I give unto those who ask me." (HR Tirmidhi and Baihaqi ).
