Ahmed Raza Khan: Mohammed Aqib Qadri:
We do not send down angels without reason, and if the angels descend they would not get any respite!

Yusuf Ali:
We send not the angels down except for just cause: if they came (to the ungodly), behold! no respite would they have!

Pickthal:
We send not down the angels save with the Fact, and in that case (the disbelievers) would not be tolerated.
