﴿ 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 among the many objects of His creation, God has appointed for you [various] means of protection: thus, He has given you in the mountains places of shelter, and has endowed you with [the ability to make] garments to protect you from heat [and cold], as well as such garments as might protect you from your [mutual] violence. In this way does He bestow the full measure of His blessings on you, so that you might surrender yourselves unto Him.”

(And Allah hath given you, of that which He hath created) from trees, gardens and mountains, (shelter from the sun) from heat; (and hath given you places of refuge) caves and grottos (in the mountains, and hath given you coats to ward off the heat from you) in the summer and cold in the winter, (and coats (of armour) to save you from your own foolhardiness) from the arms of your own enemies. (Thus doth He perfect His favour unto you, in order that ye may surrender (unto Him)) in order that you believe; it is also said that this means: in order that you be safe from injury, according to another reading.
