فَهَزَموهُم بِإِذنِ اللَّهِ وَقَتَلَ داوودُ جالوتَ وَآتاهُ اللَّهُ المُلكَ وَالحِكمَةَ وَعَلَّمَهُ مِمّا يَشاءُ ۗ وَلَولا دَفعُ اللَّهِ النّاسَ بَعضَهُم بِبَعضٍ لَفَسَدَتِ الأَرضُ وَلـٰكِنَّ اللَّهَ ذو فَضلٍ عَلَى العالَمينَ

With God’s permission, they defeated them. David killed Goliath, God gave him kingship and wisdom, and He taught him what He willed. If God didn’t repel some people through others, the earth would be corrupted. God is gracious to all the world.
