Deen e Hanif (Islam) has always been provoking the value of a human being

Because of that We ordained for the Children of Israel that if anyone killed a person not in retaliation of murder, or (and) to spread mischief in the land - it would be as if he killed all mankind, and if anyone saved a life, it would be as if he saved the life of all mankind. And indeed, there came to them Our Messengers with clear proofs, evidences, and signs, even then after that many of them continued to exceed the limits (e.g. by doing oppression unjustly and exceeding beyond the limits set by Allâh by committing the major sins) in the land!

al maeda 32

Permission for tayammum

O you who believe, when you rise for Salah, (prayer) wash your faces and your hands up to the elbows, and make Mash (wiping by hands) of your heads and (wash) your feet up to the ankles. If you are in a state of major impurity, cleanse yourselves well (by taking bath). If you are sick, or on a journey, or if one of you has come after relieving himself, or you have had sexual contact with women, and you find no water, then, go for some clean dust and wipe your faces and hands with it. Allah does not like to impose a problem on you; He, rather likes to cleanse you and to complete His favour upon you, so that you may be grateful.
