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 aid him [i.e., the Prophet (ﷺ)] - Allāh 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 [i.e., Muḥammad (ﷺ)] said to his companion, "Do not grieve; indeed Allāh is with us." And Allāh sent down His tranquility upon him and supported him with soldiers [i.e., angels] you did not see and made the word of those who disbelieved the lowest, while the word of Allāh - that is the highest. And Allāh is Exalted in Might and Wise.

Even if you do not help the Prophet, God helped him when the disbelievers drove him out: when the two of them were in the cave, he [Muhammad] said to his companion, ‘Do not worry, God is with us,’ and God sent His calm down to him, aided him with forces invisible to you, and brought down the disbelievers’ plan. God’s plan is higher: God is almighty and wise.
— M. A. S. Abdel Haleem
If you help him (Muhammad صلى الله عليه وسلم) not (it does not matter), for Allâh did indeed help him when the disbelievers drove him out, the second of the two; when they (Muhammad صلى الله عليه وسلم and Abu Bakr رضي الله عنه) were in the cave, he (صلى الله عليه وسلم) said to his companion (Abu Bakr رضي الله عنه): "Be not sad (or afraid), surely Allâh is with us." Then Allâh sent down His Sakînah (calmness, tranquillity, peace) upon him, and strengthened him with forces (angels) which you saw not, and made the word of those who disbelieved the lowermost, while the Word of Allâh that became the uppermost; and Allâh is All-Mighty, All-Wise.
