إِذ أَنتُم بِالعُدوَةِ الدُّنيا وَهُم بِالعُدوَةِ القُصوىٰ وَالرَّكبُ أَسفَلَ مِنكُم ۚ وَلَو تَواعَدتُم لَاختَلَفتُم فِي الميعادِ ۙ وَلـٰكِن لِيَقضِيَ اللَّهُ أَمرًا كانَ مَفعولًا لِيَهلِكَ مَن هَلَكَ عَن بَيِّنَةٍ وَيَحيىٰ مَن حَيَّ عَن بَيِّنَةٍ ۗ وَإِنَّ اللَّهَ لَسَميعٌ عَليمٌ

[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.
