42nd Ayah from Surah Al Anfal
Sahih International
[Remember] when you were on the near side of the valley, and they were on the farther side, and the caravan was lower [in position] than you. If you had made an appointment [to meet], you would have missed the appointment. But [it was] so that Allah might accomplish a matter already destined - that those who perished [through disbelief] would perish upon evidence and those who lived [in faith] would live upon evidence; and indeed, Allah is Hearing and Knowing.
Abdul Haleem
Remember when you were on the near side of the valley, and they were on the far side and the caravan was below you. If you had made an appointment to fight, you would have failed to keep it [but the battle took place] so that God might bring about something already ordained, so that those who were to die might die after seeing a clear proof, and so that those who were to live might live after seeing a clear proof- God is all hearing and all seeing.
Mohsin Khan/Hilali
(And remember) when you (the Muslim army) were on the near side of the valley, and they on the farther side, and the caravan on the ground lower than you. Even if you had made a mutual appointment to meet, you would certainly have failed in the appointment, but (you met) that Allah might accomplish a matter already ordained (in His Knowledge); so that those who were to be destroyed (for their rejecting the Faith) might be destroyed after a clear evidence, and those who were to live (i.e. believers) might live after a clear evidence. And surely, Allah is All-Hearer, All-Knower.
Taqi Usmani
(Remember) when you were on the nearest end of the valley, and they were on the farthest one, and the caravan was downwards from you. Had you made an appointment with each other, you would have disagreed about the appointment. But (it happened like this) so that Allah might accomplish what was destined to be done, so that whoever is going to perish may perish knowingly, and whoever is going to live may live knowingly. Allah is indeed All-Hearing, All-Knowing.
Pickthall
When ye were on the near bank (of the valley) and they were on the yonder bank, and the caravan was below you (on the coast plain). And had ye trysted to meet one another ye surely would have failed to keep the tryst, but (it happened, as it did, without the forethought of either of you) that Allah might conclude a thing that must be done; that he who perished (on that day) might perish by a clear proof (of His Sovereignty) and he who survived might survive by a clear proof (of His Sovereignty). Lo! Allah in truth is Hearer, Knower.
Pickthall
Remember ye were on the hither side of the valley, and they on the farther side, and the caravan on lower ground than ye. Even if ye had made a mutual appointment to meet, ye would certainly have failed in the appointment: But (thus ye met), that Allah might accomplish a matter already enacted; that those who died might die after a clear Sign (had been given), and those who lived might live after a Clear Sign (had been given). And verily Allah is He Who heareth and knoweth (all things).
