Sura al-Anfāl 8:17

فَلَمْ تَقْتُلُوهُمْ وَلَٰكِنَّ ٱللَّـهَ قَتَلَهُمْ وَمَا رَمَيْتَ إِذْ رَمَيْتَ وَلَٰكِنَّ ٱللَّـهَ رَمَىٰ وَلِيُبْلِىَ ٱلْمُؤْمِنِينَ مِنْهُ بَلَآءً حَسَنًا إِنَّ ٱللَّـهَ سَمِيعٌ عَلِيمٌ

falam taqtulūhum wa-lākinna allāha qatalahum wa-mā ramayta idh ramayta wa-lākinna allāha rama wa-li-yubliya l-muʾminīna minhu balāʾan ḥasanan inna allāha samīʿun ʿalīmun

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).
