سورة Al-Anfal ( The Spoils of War ) - الآية 17

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.
