No doubt life in its forms enjoys a very high status in Islam. God Himself is characterised as "the Living". Among the creature, human life is one of the most sacred ones and has the potentiality of becoming the most sacred one. As a result, great attention had been attached to human life to the extent that the respect for human life starts much earlier than actual birth and this continues to the period after death.Though the main aspect of human reality is the spirit, this respect extends to the body as well. Human life must be regulated according to divine instructions, that is, to its best and towards a fully human one.Therefore, it must be appreciated, respected and protected.In this paper, I will study how this protection is regulated in Islamic law and bioethics and what the difference between the legal and the ethical approaches is. Maintenance of physical health and treatment' of the sick are two important aspects of Islamic teachings in this regard. In respect to the beginning of human life, firstly we will see that reproduction must occur in the context of a legitimate and stable family.Secondly we will see how abortion is viewed in Islamic law and bioethics.In respect to the end of life, issues such as heath, suicide and euthanasia will be studied.
