فَهَزَمُوهُم بِإِذۡنِ ٱللَّهِ وَقَتَلَ دَاوُۥدُ جَالُوتَ وَءَاتَىٰهُ ٱللَّهُ ٱلۡمُلۡكَ وَٱلۡحِكۡمَةَ وَعَلَّمَهُۥ مِمَّا يَشَآءُۗ وَلَوۡلَا دَفۡعُ ٱللَّهِ ٱلنَّاسَ بَعۡضَهُم بِبَعۡضٖ لَّفَسَدَتِ ٱلۡأَرۡضُ وَلَٰكِنَّ ٱللَّهَ ذُو فَضۡلٍ عَلَى ٱلۡعَٰلَمِينَ ٢٥١
Fahazamūhum biʾidhnillāhi wa qatala dāwūdu jālūta wa ātāhullāhul-mulka wal-ḥikmata wa ʿallamahū mimmā yashāʾ, wa lawlā dafʿullāhin-nāsa baʿḍahum bibaʿḍil lafasadatil-arḍu wa lākinnallāha dhū faḍlin ʿalal-ʿālamīn.
So they defeated them by permission of Allāh, and David killed Goliath, and Allāh gave him the kingship and wisdom [i.e., prophethood] and taught him from that which He willed. And if it were not for Allāh checking [some] people by means of others, the earth would have been corrupted, but Allāh is the possessor of bounty for the worlds.
