The Holy Quran 2:251 — Surah Al-Baqarah
Arabic text
فَهَزَمُوهُم بِإِذْنِ ٱللَّهِ وَقَتَلَ دَاوُۥدُ جَالُوتَ وَءَاتَىٰهُ ٱللَّهُ ٱلْمُلْكَ وَٱلْحِكْمَةَ وَعَلَّمَهُۥ مِمَّا يَشَآءُ ۗ وَلَوْلَا دَفْعُ ٱللَّهِ ٱلنَّاسَ بَعْضَهُم بِبَعْضٍ لَّفَسَدَتِ ٱلْأَرْضُ وَلَـٰكِنَّ ٱللَّهَ ذُو فَضْلٍ عَلَى ٱلْعَـٰلَمِينَ
Translation
So they (the Mu'mineen) defeated them (the Kuffaar) by the order of Allaah. Daawood عليه الصلاة والسلام (who was a soldier in Taaloot's army) killed Jaaloot (using a catapult and three stones) and Allaah granted him (Dawood عليه الصلاة والسلام) kingship and wisdom, and taught him that which He willed (like the ability to speak to birds). If Allaah had not repelled (driven back) some men by others, the earth would have been corrupted (because the Mu'mineen would have been killed and Masaajid destroyed). However, Allaah is the One Who showers grace on the universe.
Tafsir (excerpt) — Tafsir Usmani
The defeat of Jalut: when they came face to face with Jalut, that is, those same three hundred and thirteen men, and among these three hundred and thirteen were the father of Dawud ﵇, six of his brothers and Dawud ﵇ himself, on the way Dawud ﵇ came across three stones, which said: pick us up, we will kill Jalut.
