2:251
فَ هَزَمُ و هُم بِ إِذْنِ ٱللَّهِ وَ قَتَلَ دَاوُۥدُ جَالُوتَ وَ ءَاتَىٰ هُ ٱللَّهُ ٱلْ مُلْكَ وَ ٱلْ حِكْمَةَ وَ عَلَّمَ هُۥ مِ مَّا يَشَآءُ وَ لَوْلَا دَفْعُ ٱللَّهِ ٱل نَّاسَ بَعْضَ هُم بِ بَعْضٍ لَّ فَسَدَتِ ٱلْ أَرْضُ وَ لَٰكِنَّ ٱللَّهَ ذُو فَضْلٍ عَلَى ٱلْ عَٰلَمِينَ
So they defeated them by permission of Allah, and David killed Goliath, and Allah gave him the kingship and prophethood and taught him from that which He willed. And if it were not for Allah checking [some] people by means of others, the earth would have been corrupted, but Allah is full of bounty to the worlds.
38:11
جُندٌ مَّا هُنَالِكَ مَهْزُومٌ مِّنَ ٱلْ أَحْزَابِ
[They are but] soldiers [who will be] defeated there among the companies [of disbelievers].
54:45
سَ يُهْزَمُ ٱلْ جَمْعُ وَ يُوَلُّ ونَ ٱل دُّبُرَ
[Their] assembly will be defeated, and they will turn their backs [in retreat].
