And Lord Allah has made for you shadows from that which He has created and has made for you shelters from the mountains, and has made for you garments which protect you from the heat and garments which protect you from your enemy. Thus does He complete His favor upon you, so that you may submit wholly to Him.
In deserts, shadows of camels and tents are used for taking rest. Mountains serve as borders and shelters. Garments are used for protection from high and low temperatures. Bulletproof vests, flame-resistant clothes, water-resistant suites, different types of masks, etc. are developed nowadays. All these are already decided and are recorded by the Lord of the universe in Adhikr as explained in verse 2: 255. So believer who testifies Adhikr will only submit whole to Lord whereas the Arabic Quran reading hypocrites and Kuffar are the true disbelievers serving Satan as explained in verse 16: 89. See explanation 3: 83-85, 190-191; 9: 32 and 16: 18.
