Al-Qadr - 97:4

تَنَزَّلُ الْمَلَائِكَةُ وَالرُّوحُ فِيهَا بِإِذْنِ رَبِّهِم مِّن كُلِّ أَمْرٍ
[97:4]
The angels and Gibreel descend in it by the permission of their Lord for every affair,
Therein come down the angels and the Spirit by Allah's permission, on every errand:
The angels and the Spirit descend therein, by the permission of their Lord, with all decrees.
