Q 3:
Is it permissible for a Muslim to offer Janazah (Funeral) Prayer over a Kafir (disbeliever) when he dies?
A:
It is permissible neither to offer Janazah Prayer over a deceased Kafir nor to supplicate Allah for him. Allah (Exalted be He) says:
It is not (proper) for the Prophet and those who believe to ask Allâh’s Forgiveness for the Mushrikûn (polytheists, idolaters, pagans, disbelievers in the Oneness of Allâh), even though they be of kin
