40th Ayah from Surah At Tawbah
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.
Abdul Haleem
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.
Mohsin Khan/Hilali
If you help him (Muhammad SAW) not (it does not matter), for Allah did indeed help him when the disbelievers drove him out, the second of two, when they (Muhammad SAW and Abu Bakr) were in the cave, and he (SAW) said to his companion (Abu Bakr): "Be not sad (or afraid), surely Allah is with us." Then Allah sent down His Sakinah (calmness, tranquillity, peace, etc.) upon him, and strengthened him with forces (angels) which you saw not, and made the word of those who disbelieved the lowermost, while it was the Word of Allah that became the uppermost, and Allah is All-Mighty, All-Wise.
Taqi Usmani
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.
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.
Pickthall
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.
