تَنَزَّلُ الْمَلَائِكَةُ وَالرُّوحُ فِيهَا بِإِذْنِ رَبِّهِم مِّن كُلِّ أَمْرٍ (4)
(97:4) The angels along with the Spirit *3 descend in it by the permission of their Lord *4 with all kinds of decrees.
*3) "The Spirit": Gabriel (peace be on him), who has been mentioned separately from the angels in view of his unique eminence, honour and merit.
*4) That is, they do not descend of their own accord but by leave of their Lord, and "every decree" implies amr hakim (a wise decree) as described in Ad-Dukhan: 5.
