Yusuf Ali
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.

Sahih International
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.

Shakir
If you will not aid him, Allah certainly aided him when those who disbelieved expelled him, he being the second of the two, when they were both in the cave, when he said to his companion: Grieve not, surely Allah is with us. So Allah sent down His tranquillity upon him and strengthened him with hosts which you did not see, and made lowest the word of those who disbelieved; and the word of Allah, that is the highest; and Allah is Mighty, Wise.

Pickthall
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.

محمد جالندھری
اگر تم پیغمبر کی مدد نہ کرو گے تو خدا اُن کا مددگار ہے (وہ وقت تم کو یاد ہوگا) جب ان کو کافروں نے گھر سے نکال دیا۔ (اس وقت) دو (ہی ایسے شخص تھے جن) میں (ایک ابوبکرؓ تھے) اور دوسرے (خود رسول الله) جب وہ دونوں غار (ثور) میں تھے اس وقت پیغمبر اپنے رفیق کو تسلی دیتے تھے کہ غم نہ کرو خدا ہمارے ساتھ ہے۔ تو خدا نے ان پر تسکین نازل فرمائی اور ان کو ایسے لشکروں سے مدد دی جو تم کو نظر نہیں آتے تھے اور کافروں کی بات کو پست کر دیا۔ اور بات تو خدا ہی کی بلند ہے۔ اور خدا زبردست (اور) حکمت والا ہے
