At-Tawbah 9:40 الا تنصروه فقد نصره الله اذ اخرجه الذين كفروا ثاني اثنين اذ هما في الغار اذ يقول لصاحبه لا تحزن ان الله معنا فانزل الله سكينته عليه وايده بجنود لم تروها وجعل كلمة الذين كفروا السفلى وكلمة الله هي العليا والله عزيز حكيم ٤٠

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.

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,¹ 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 word² of those who disbelieved the lowest,³ while the word of Allāh⁴ - that is the highest. And Allāh is Exalted in Might and Wise.

If ye help not (your leader), (it is no matter): for Allah did indeed help him, when the Unbelievers drove him out: he had no more than one companion; they two were in the cave, and he said to his companion, "Have no fear, for Allah is with us": then Allah sent down His peace upon him, and strengthened him with forces which ye saw not, and humbled to the depths the word of the Unbelievers. But the word of Allah is exalted to the heights: for Allah is Exalted in might, Wise.
