Al-Anfaal 8:17

It was not you who killed them, but it was Allah Who killed them; and it was not you [O Prophet] who threw when you threw [a handful of sand][8] but it was Allah Who threw, so that He might test the believers with a great test. Allah is All-Hearing, All-Knowing.

[8] It filled their eyes and noses, preventing their advance.

And you did not kill them, but it was Allāh who killed them.[440] And you threw not, [O Muḥammad], when you threw, but it was Allāh who threw[441] that He might test the believers with a good test.[442] Indeed, Allāh is Hearing and Knowing.

[440] i.e., Your strength was insufficient to overcome them, but Allāh supported you and gave you victory.
[441] When the Prophet (ﷺ) threw a handful of dust into the faces of the disbelievers, Allāh caused it to fill the eyes and nose of every soldier, preventing their advance.
[442] So that they would appreciate Allāh's favor to them.

17. You killed them not, but Allâh killed them. And you (Muhammad صلى الله عليه وسلم) threw not when you did throw, but Allâh threw, that He might test the believers by a fair trial from Him. Verily, Allâh is All-Hearer, All-Knower.

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.
