Chapter 8, Verse 43

When you were on the nearer bank of the valley, and they were on the farther bank, and the caravan was below you. And if you had to make a mutual appointment, you would have certainly differed with regard to the appointment. But the encounter was brought about that Allah might accomplish the thing that was decreed; so that he who had already perished through a clear Sign might perish, and he who had already come to life through a clear Sign might live. And certainly Allah is All-Hearing, All-Knowing.
