Ahmed Raza Khan: Mohammed Aqib Qadri:
So you did not slay them, but in fact Allah slew them; and O dear Prophet (Mohammed - peace and blessings be upon him) you did not throw (the sand) when you did throw, but in fact Allah threw; and in order to bestow an excellent reward upon the Muslims; indeed Allah is the All Hearing, the All Knowing.

Yusuf Ali:
It is not ye who slew them; it was Allah: when thou threwest (a handful of dust), it was not thy act, but Allah's: in order that He might test the Believers by a gracious trial from Himself: for Allah is He Who heareth and knoweth (all things).

Pickthal:
Ye (Muslims) slew them not, but Allah slew them. And thou (Muhammad) threwest not when thou didst throw, but Allah threw, that He might test the believers by a fair test from Him. Lo! Allah is Hearer, Knower.
