The Islamic Fiqh Council of the Muslim World League, in its seventeenth conference in Makkah al-Mukarramah, 2003 CE, discussed the topic of transplanting stem cells on the basis of the sources of these cells. The Council took the following decision: it is permissible to obtain stem cells and grow them, and use them for medical treatment or permissible scientific research, if the sources are permissible. That includes, for example, the following sources:
Adults if they have given permission and that will not cause any harm.
Children, if their guardians have given permission, if it is done for a legitimate purpose and without harm
Placentas and umbilical cords, with the permission of the parents.
Spontaneously aborted foetuses (i.e., miscarriage) or foetuses from abortions that were carried out for medical reasons permitted by sharee‘ah, with the permission of the parents.
