64وَما نَتَنَزَّلُ إِلّا بِأَمرِ رَبِّكَ ۖ لَهُ ما بَينَ أَيدينا وَما خَلفَنا وَما بَينَ ذٰلِكَ ۚ وَما كانَ رَبُّكَ نَسِيًّاN. J. DawoodWe descend only at the bidding of Your Lord.1 To Him belongs what is before us and behind us, and all that lies between. Your Lord does not forget.Commentators say that these are the words of the Angel Gabriel, in reply to Muḥammad’s complaint of long intervals elapsing between periods of revelation.
