A. Yusuf Ali:Translation:
O you who believe! Take your precautions, and either
go forth in parties or go forth all together. 588

Muhammad Asad:Translation:
O YOU who have attained to faith! Be fully prepared against danger, whether you go to war in small groups or all together. 87
588 No fight should be undertaken without due preparations and precautions. When these are taken, we must go boldly forward. "Go forth" is therefore repeated for emphasis. But we must go forth in a collective spirit-either in small parries or all together, as our Leader determines. We must not tarry like the doubter in the next two verses.
