Wajaa rabbuka walmalaku saffan saffa (surah Fajr: 22)

Tafseer Tafheem-ul-Quran by Syed Abu-al-A'la Maududi

(89:22) and when your Lord appears *16 with rows upon rows of angels,

Wa jaaa`a Rabbuka wal malaku saffan saffaa

*16) Although literally the words jaa Rabbuka mean "your Lord will come", obviously there cannot be any question of Allah Almighty's moving from one place to another; therefore, this will inevitably have to be understood as au allegoric expression, which is meant to give an idea that at that time the manifestations of Allah Almighty's power and His majesty and sovereignty will appear fully, as, for example, in the world the arrival of a king in person in the court is more awe-inspiring than the mere array of his forces and chiefs and nobles.
