The Ruling on Praying for the Disbeliever or Against Him
Question :
Do we supplicate and ask for death, destruction, and punishment for the apostate and the disbeliever. Or do we ask for them to become guided? When do we pray for them and when do we pray against them?
Answer:
If the apostate is causing harm for Allâh's servants and if A he is wronging them, then there is no harm in supplicating and asking for his destruction, in order to be saved from his harm.
If this is not the case, then it is better to supplicate and ask for his guidance. Those who are vested with authority (the ruler) must invite the apostate to Islam, to warn him for a period that does not exceed three days. Or, if they feel that it is more appropriate, they can forego the three-day delay and kill the apostate immediately. If the ruler does give the apostate three days, and the three days pass without him returning to Islam, it becomes compulsory to kill him. The Prophet ﷺ said:
"Whosoever exchanges his religion, kill him."
The case of the disbeliever, in terms of supplication either for or against him, is the same as the apostate.
