Amatul Rahmân Omer:
Therefore (in this war O Muslims!) you killed them not. (As a matter of fact) it was Allâh Who killed them. And (O Prophet!) it was not you who threw (a handful of small stones) when you did (apparently) throw them (towards the enemy) but it was Allâh Who threw (that He might vanquish your enemies) and that He might confer on the believers from Himself a bounteous favour. Verily, Allâh is All-Hearing, All-Knowing.
