فَهَزَمُوهُم بِإِذْنِ ٱللَّهِ وَقَتَلَ دَاوُۥدُ جَالُوتَ وَءَاتَىٰهُ ٱللَّهُ ٱلْمُلْكَ وَٱلْحِكْمَةَ وَعَلَّمَهُۥ مِمَّا يَشَآءُ ۗ وَلَوْلَا دَفْعُ ٱللَّهِ ٱلنَّاسَ بَعْضَهُم بِبَعْضٍۢ لَّفَسَدَتِ ٱلْأَرْضُ وَلَٰكِنَّ ٱللَّهَ ذُو فَضْلٍ عَلَى ٱلْعَٰلَمِينَ
So they routed them by Allah's leave and David slew Goliath; and Allah gave him the kingdom and wisdom, and taught him of that which He willeth. And if Allah had not repelled some men by others the earth would have been corrupted. But Allah is a Lord of Kindness to (His) creatures.
