وَمَا نَتَنَزَّلُ إِلَّا بِأَمْرِ رَبِّكَ ۖ لَهُۥ مَا بَيْنَ أَيْدِينَا وَمَا خَلْفَنَا وَمَا بَيْنَ ذَٰلِكَ ۚ وَمَا كَانَ رَبُّكَ نَسِيًّۭا
We (angels) come not down save by commandment of thy Lord. Unto Him belongeth all that is before us and all that is behind us and all that is between those two, and thy Lord was never forgetful -
