Surah Al-Anfal (The Spoils of War), Verse 42

اِذْ اَنْتُمْ بِالْعُدْوَةِ الدُّنْیَا وَهُمْ بِالْعُدْوَةِ الْقُصْوٰی وَالرَّكْبُ اَسْفَلَ مِنْكُمْ وَلَوْ تَوَاعَدْتُّمْ لَاخْتَلَفْتُمْ فِی الْمِیْعٰدِ وَلٰكِنْ لِّیَقْضِیَ اللّٰهُ اَمْرًا كَانَ مَفْعُوْلًا لِّیَهْلِكَ مَنْ هَلَكَ عَنْ بَیِّنَةٍ وَّیَحْیٰی مَنْ حَیَّ عَنْ بَیِّنَةٍ وَاِنَّ اللّٰهَ لَسَمِیْعٌ عَلِیْمٌ ۟

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 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).”
