At Tawbah Ayah 40

إِلَّا تَنصُرُوهُ فَقَدْ نَصَرَهُ ٱللَّهُ إِذْ أَخْرَجَهُ ٱلَّذِينَ كَفَرُواْ ثَانِىَ ٱثْنَيْنِ إِذْ هُمَا فِى ٱلْغَارِ إِذْ يَقُولُ لِصَـٰحِبِهِۦ لَا تَحْزَنْ إِنَّ ٱللَّهَ مَعَنَا‌ۖ فَأَنزَلَ ٱللَّهُ سَكِينَتَهُۥ عَلَيْهِ وَأَيَّدَهُۥ بِجُنُودٍ لَّمْ تَرَوْهَا وَجَعَلَ كَلِمَةَ ٱلَّذِينَ كَفَرُواْ ٱلسُّفْلَىٰ‌ۗ وَكَلِمَةُ ٱللَّهِ هِىَ ٱلْعُلْيَا‌ۗ وَٱللَّهُ عَزِيزٌ حَكِيمٌ ٤٠ ?It does not matter? if you ?believers? do not support him, for Allah did in fact support him when the disbelievers drove him out ?of Mecca? and he was only one of two. While they both were in the cave, he reassured his companion, “Do not worry; Allah is certainly with us.” So Allah sent down His serenity upon the Prophet, supported him with forces you ?believers? did not see, and made the word of the disbelievers lowest, while the Word of Allah is supreme. And Allah is Almighty, All-Wise.
