It is not permissible for a Muslim to take possession of any non-Muslim person if the infidels attack Islamic lands and a group of them are captured by Muslims.
Question: Is it permissible for a Muslim to take possession of any non-Muslim person whether kitābī or non-kitābī, man or woman, in a non-Muslim country or in an Islamic one?
Answer: It is not permissible. In case the infidels attack Islamic lands and a group of them are captured by Muslims, deciding the fate of the prisoners of war rests with the Islamic ruler and Muslims as individuals do not have such powers.[1]
