At-Táuba 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 you do not help him, (it makes no difference to the Prophet, because) Allah has already helped him when the disbelievers expelled him, and he was the second of the two, when they were in the cave, and he was saying to his companion, “Do not grieve. Allah is surely with us.”So, Allah caused His tranquility to descend on him,and supported him with troops that you did not see, and rendered the word of the disbelievers humiliated. And the word of Allah is the uppermost. Allah is Mighty, Wise.
