O you who have believed, remember the favor of Allāh upon you when armies came to [attack] you and We sent upon them a wind and armies [of angels] you did not see. And ever is Allāh, of what you do, Seeing.

O you who believe, remember Allah’s favor to you, when the forces (of the infidels) came upon you, and We sent upon them a wind, and the forces (of angels) you did not see. Allah is watchful of whatever you do.
