2. Sun protection

The Prophet(~ ) said: «If one of you was in the shade and then the shade receded and exposed a part of his body to the sun, let him move from that place.»44 The most common cause of skin cancer is excessive exposure to the damaging effects of UV radiation from the sun. There are two types of UV radiation: UV A, which has a long wave length, and UVB radiation, which has a shorter, more damaging wavelength and which is mainly responsible for skin lesions. For your safety, you should avoid direct exposure to sunlight during the hours of the day when (in your part of the world) the sun's rays are most harmful. That is why Allah (~) specified shade as one of His great blessings: 44 Abu Dawood and A):imed (sound according to Albani). ~And Allah has made for you that from which He has created shade, and has made for you places of refuge in the mountains, and has made for you garments to protect you from the heat..) (Quran 16: 81)
