(Ambiya') 21 : 27
لَا يَسْبِقُونَهُ بِالْقَوْلِ وَهُمْ بِأَمْرِهِ يَعْمَلُونَ
They cannot precede Him in Word, and they act by His Command.
Angels are those who will never disobey Lord and they are doing whatever they are commanded with as explained in verse 21: 19. Whoever holdfasts Adhikr, he did holdfast Lord and is guided into Straightpath as explained in verses 2: 256; 3: 101; 4: 174-175 and 5: 48. See explanation 4: 172; 16: 50; 19: 64.
