Surah Al-Anfal (The Spoils of War), Verse 17

فَلَمْ تَقْتُلُوْهُمْ وَلٰكِنَّ اللّٰهَ قَتَلَهُمْ وَمَا رَمَیْتَ اِذْ رَمَیْتَ وَلٰكِنَّ اللّٰهَ رَمٰی وَلِیُبْلِیَ الْمُؤْمِنِیْنَ مِنْهُ بَلَآءً حَسَنًا اِنَّ اللّٰهَ سَمِیْعٌ عَلِیْمٌ ۟

Falam taqtuloohum wa laakinnal laaha qatalahum; wa maa ramaita iz ramaita wa laakinnal laaha ramaa; wa liyubliyal mu'mineena minhu balaaa'an hasanaa; innal laaha Samee'un Aleem

“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).”
