اِلَّا تَنْصُرُوهُ فَقَدْ نَصَرَهُ اللّٰهُ اِذْ اَخْرَجَهُ الَّذٖینَ كَفَرُوا ثَانِیَ اثْنَیْنِ اِذْ هُمَا فِی الْغَارِ اِذْ یَقُولُ لِصَاحِبِهٖ لَا تَحْزَنْ اِنَّ اللّٰهَ مَعَنَاۚ فَاَنْزَلَ اللّٰهُ سَكٖینَتَهُ عَلَیْهِ وَاَیَّدَهُ بِجُنُودٍ لَمْ تَرَوْهَا وَجَعَلَ كَلِمَةَ الَّذٖینَ كَفَرُوا السُّفْلٰىؕ وَكَلِمَةُ اللّٰهِ هِیَ الْعُلْیَاؕ وَاللّٰهُ عَزٖیزٌ حَكٖیمٌ

Translations
If you do not aid the Prophet - Allah has already aided him when those who disbelieved had driven him out [of Makkah] as one of two, when they were in the cave and he said to his companion, "Do not grieve; indeed Allah is with us." And Allah sent down his tranquillity upon him and supported him with angels you did not see and made the word of those who disbelieved the lowest, while the word of Allah - that is the highest. And Allah is Exalted in Might and Wise
Saheeh International
If ye help him not, still Allah helped him when those who disbelieve drove him forth, the second of two; when they two were in the cave, when he said unto his comrade: Grieve not. Lo! Allah is with us. Then Allah caused His peace of reassurance to descend upon him and supported him with hosts ye cannot see, and made the word of those who disbelieved the nethermost, while Allah's Word it was that became the uppermost. Allah is Mighty, Wise
