Praise be to Allah.
If there are people among the kuffaar who can bury their own dead, then the Muslims should not bury them, or join the kuffaar and help them to bury them, or try to please the kuffaar by joining the funeral procession, even if this is a political practice. Such things are not known from the Messenger of Allaah (peace and blessings of Allaah be upon him) or the Khulafaa’ al-Raashidoon. In fact, Allaah forbade His Messenger (peace and blessings of Allaah be upon him) to stand by the grave of ‘Abd-Allaah ibn Ubayy ibn Salool, and explained that the reason for this prohibition was that the man was a kaafir. Allaah said (interpretation of the meaning):
“And never (O Muhammad) pray (funeral prayer) for any of them (hypocrites) who dies, nor stand at his grave. Certainly they disbelieved in Allaah and His Messenger, and died while they were Faasiqoon (rebellious, disobedient to Allaah and His Messenger).” [al-Tawbah 9:84]
If there is nobody among them who can bury their dead, then the Muslims should bury them, as the Prophet (peace and blessings of Allaah be upon him) did with those who were killed at Badr, and as he did with his uncle Abu Taalib, when he died, and he [the Prophet (peace and blessings of Allaah be upon him)] said to ‘Ali: “Go and bury him.”
And Allaah is the Source of strength. May Allaah bless our Prophet Muhammad and his family and companions, and grant them peace.
