وَمَا نَتَنَزَّلُ إِلَّا بِأَمْرِ رَبِّكَ ۖ لَهُۥ مَا بَيْنَ أَيْدِينَا وَمَا خَلْفَنَا وَمَا بَيْنَ ذَٰلِكَ ۚ وَمَا كَانَ رَبُّكَ نَسِيًّا

And we do not descend but by the command of your Lord; to Him belongs whatever is before us and whatever is behind us and whatever is between these, and your Lord is not forgetful.
