Surah Al-Anfaal, Verse 42
إِذْ أَنتُم بِٱلْعُدْوَةِ ٱلدُّنْيَا وَهُم بِٱلْعُدْوَةِ ٱلْقُصْوَىٰ وَٱلرَّكْبُ أَسْفَلَ مِنكُمْ ۚ وَلَوْ تَوَاعَدتُّمْ لَٱخْتَلَفْتُمْ فِى ٱلْمِيعَٰدِ ۙ وَلَٰكِن لِّيَقْضِىَ ٱللَّهُ أَمْرًۭا كَانَ مَفْعُولًۭا لِّيَهْلِكَ مَنْ هَلَكَ عَنۢ بَيِّنَةٍۢ وَيَحْيَىٰ مَنْ حَىَّ عَنۢ بَيِّنَةٍۢ ۗ وَإِنَّ ٱللَّهَ لَسَمِيعٌ عَلِيمٌ
Translation — 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.
