Verse 40

إِلَّا تَنصُرُوهُ فَقَدْ نَصَرَهُ ٱللَّهُ إِذْ أَخْرَجَهُ ٱلَّذِينَ كَفَرُوا۟ ثَانِىَ ٱثْنَيْنِ إِذْ هُمَا فِى ٱلْغَارِ إِذْ يَقُولُ لِصَـٰحِبِهِۦ لَا تَحْزَنْ إِنَّ ٱللَّهَ مَعَنَا فَأَنزَلَ ٱللَّهُ سَكِينَتَهُۥ عَلَيْهِ وَأَيَّدَهُۥ بِجُنُودٍ لَّمْ تَرَوْهَا وَجَعَلَ كَلِمَةَ ٱلَّذِينَ كَفَرُوا۟ ٱلسُّفْلَىٰ وَكَلِمَةُ ٱللَّهِ هِىَ ٱلْعُلْيَا وَٱللَّهُ عَزِيزٌ حَكِيمٌ

If you do not help him, then God has surely helped him when the unfaithful evicted him and he was one of the two in the cave; he said to his friend, do not grieve because God is with us. Thereafter, God sent down His tranquility upon him and helped him with invisible armies and made the word of the unfaithful lowly as the word of God reigned supreme. And God is Almighty, All Wise.
