Yusuf Ali
Remember in thy dream Allah showed them to thee as few: if He had shown them to thee as many, ye would surely have been discouraged, and ye would surely have disputed in (your) decision; but Allah saved (you): for He knoweth well the (secrets) of (all) hearts.

Sahih International
[Remember, O Muhammad], when Allah showed them to you in your dream as few; and if He had shown them to you as many, you [believers] would have lost courage and would have disputed in the matter [of whether to fight], but Allah saved [you from that]. Indeed, He is Knowing of that within the breasts.

Shakir
When Allah showed them to you in your dream as few; and if He had shown them to you as many you would certainly have become weak-hearted and you would have disputed about the matter, but Allah saved (you); surely He is the Knower of what is in the breasts.

Pickthall
When Allah showed them unto thee (O Muhammad) in thy dream as few in number, and if He had shown them to thee as many, ye (Muslims) would have faltered and would have quarrelled over the affair. But Allah saved (you). Lo! He knoweth what is in the breasts (of men).
