Surah Al-Anfal · Ayah 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

Iz antum bil'udwatid dunyaa wa hum bil'udwatil quswaa warrakbu asfala minkum; wa law tawaa'attum lakhtalaftum fil mee'aadi wa laakil liyaqdiyal laahu amran kaana maf'oolal liyahlika man halaka 'am baiyinatinw wa yahyaa man haiya 'am baiyinah; wa innal laaha la Samee'un 'Aleem

[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.
