Quran 16:81

وَٱللَّهُ جَعَلَ لَكُم مِّمَّا خَلَقَ ظِلَـٰلاً۬ وَجَعَلَ لَكُم مِّنَ ٱلۡجِبَالِ أَڪۡنَـٰنً۬ا وَجَعَلَ لَكُمۡ سَرَٲبِيلَ تَقِيڪُمُ ٱلۡحَرَّ وَسَرَٲبِيلَ تَقِيكُم بَأۡسَڪُمۡ‌ۚ كَذَٲلِكَ يُتِمُّ نِعۡمَتَهُ ۥ عَلَيۡڪُمۡ لَعَلَّكُمۡ تُسۡلِمُونَ ٨١

And ALLAH provided for you shade through things which He created, and provided for you shelters in the mountains, and provided for you garments that protect you from heat, and garments that protect when you fight in wars. He thus perfects His blessings upon you, that you may submit.
