Surah 9 : Ayah 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 support the Prophet, Allah has already supported him when the disbelievers forced him out; when he was second of the two[38] in the cave – saying to his companion, “Do not grieve; Allah is with us.” Thereupon Allah sent down His tranquility upon him, supported him with soldiers that you did not see[39], and rendered the word of the disbelievers[40] the lowest, whereas the Word of Allah[41] is supreme. And Allah is All-Mighty, All-Wise.
