If an individual is killed, and it is not possible to find out about the killer except through post mortem examination by dissecting the body of the deceased, is dissection then permissible in order to find out about the killer?
If finding out about the killer is by no means possible except through autopsy, there is no objection to that.
If there is a probability of finding out about the killer through an autopsy, is dissection permissible with this probability only?
If the probability is plausible (and the way forward is dependent on it) then there is no objection.
What is the duty of a Muslim student who studies in a Muslim country when a corpse is being dissected in front of him and he does not know whether or not it is of a Muslim?
If it is out of compulsion, there is no objection to that, even if the compulsion is [not absolute and it is only] out of competing priority in the view of the Shari‘ah.
I am a university lecturer in the autopsy department. Is it permissible for me to dissect the corpses of the deceased with prior permission from them before death, or with the permission of their next of kin, given that dissection is for teaching purposes?
It is not permissible, and this should instead be done with animals that have resemblance in their body parts to humans. If there is compulsion to do so, then it should be done with the corpses of the non- Muslim, with their prior permission. As for the Muslim dead, it is not permissible.
