Question:
He asks: Is it permissible to pray over a deceased person if he died while not praying?
Answer:
If it is established that he did not pray and did not repent to Allah, and he died without repenting to Allah, and you are certain of this, then do not pray over him. But if you do not know, if you do not know about his end or his state, and you only suspect him of it, mere suspicion, then the default for a Muslim is good and the default for him is integrity, if Allah wills, so pray over him as long as you are not certain that he died upon disbelief and shirk (associating partners with Allah) or abandoning the prayer. Yes.
