Human cloning is a new phenomenon that is still in the early amazing stage. In biology, cloning means “proliferation of a living creature without sexual intercourse” and is currently referred to embryonic implantation in the womb which is originally produced in the laboratory. In other words, cloning is the creation of a genetically identical copy of a human or animal that, by replacing the core of the referred person’s cell and multiplying it, results in the production of a person exactly identical (or a copy) of the first person. The process is that researchers first replace nuclei of an ovum with DNA of other cells, then protect them in the laboratory to proliferate and change to embryos. If the embryo is implanted in the womb and a human being is born, human reproduction has done. I view of Islamic jurists; human cloning is forbidden for many reasons. The present paper tries to study the cloning issue, its negative and positive consequences, and the reactions that have been shown in the world of Christianity and the West and Islamic world.
