Islamic Hijri calendar for the month of Dhu Al-Qidah of the year 1150 AH

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

When ye were on the near bank (of the valley) and they were on the yonder bank, and the caravan was below you (on the coast plain). And had ye trysted to meet one another ye surely would have failed to keep the tryst, but (it happened, as it did, without the forethought of either of you) that Allah might conclude a thing that must be done; that he who perished (on that day) might perish by a clear proof (of His Sovereignty) and he who survived might survive by a clear proof (of His Sovereignty). Lo! Allah in truth is Hearer, Knower.

Surah Al-Anfaal(8:42)
