وَٱللَّهُ جَعَلَ لَكُم مِّمَّا خَلَقَ ظِلَٰلًۭا وَجَعَلَ لَكُم مِّنَ ٱلْجِبَالِ أَكْنَٰنًۭا وَجَعَلَ لَكُمْ سَرَٰبِيلَ تَقِيكُمُ ٱلْحَرَّ وَسَرَٰبِيلَ تَقِيكُم بَأْسَكُمْ ۚ كَذَٰلِكَ يُتِمُّ نِعْمَتَهُۥ عَلَيْكُمْ لَعَلَّكُمْ تُسْلِمُونَ
And Allah hath given you, of that which He hath created, shelter from the sun; and hath given you places of refuge in the mountains, and hath given you coats to ward off the heat from you, and coats (of armour) to save you from your own foolhardiness. Thus doth He perfect His favour unto you, in order that ye may surrender (unto Him).
Surah An-Nahl(16:81)
