All kind of true and perfect praise belongs to Allâh, the Originator of the heavens and the earth, Who employs as (His) messengers the angels, having two or three or four pairs of wings (and so possessed of powers, speed and qualities in varying degrees). He adds to the creation (of these wings and thus to the powers and abilities of the angels) as much as He will (in accordance with the importance of the work entrusted to each one of them), for Allâh is Possessor of power over (His) every desired thing.
