Quran 9:40 from Surah At-Tawba on Divine Marvels.
إِلَّا تَنصُرُوهُ فَقَدۡ نَصَرَهُ ٱللَّهُ إِذۡ أَخۡرَجَهُ ٱلَّذِينَ كَفَرُواْ ثَانِيَ ٱثۡنَيۡنِ إِذۡ هُمَا فِي ٱلۡغَارِ إِذۡ يَقُولُ لِصَٰحِبِهِۦ لَا تَحۡزَنۡ إِنَّ ٱللَّهَ مَعَنَاۖ فَأَنزَلَ ٱللَّهُ سَكِينَتَهُۥ عَلَيۡهِ وَأَيَّدَهُۥ بِجُنُودٖ لَّمۡ تَرَوۡهَا وَجَعَلَ كَلِمَةَ ٱلَّذِينَ كَفَرُواْ ٱلسُّفۡلَىٰۗ وَكَلِمَةُ ٱللَّهِ هِيَ ٱلۡعُلۡيَاۗ وَٱللَّهُ عَزِيزٌ حَكِيمٌ
English translation: If not you help him certainly Allah helped him Allah helped him when drove him out those who disbelieved the second (of) the two when they both (were) in the cave when he said to his companion (Do) not grieve indeed Allah (is) with us Then Allah sent down Then Allah sent down His tranquility upon him and supported him with forces which you did not see which you did not see and made (the) word (of) those who disbelieved the lowest while (the) Word (of) Allah it (is) the highest And Allah (is) All-Mighty All-Wise
