[Q]: Is it better to recite the Qurʾān at night or to sleep and then recite it during the day?
[A]: He should recite what he can by night or by day. But to recite it by night is better since that’s when Jibrīl would teach the Prophet (ṣallallāhu ʿalayhi wa-sallam) the Qurʾān.
Dr. Ṣaliḥ ibn al-Fawzān
