Following the funeral of a disbeliever and preparing food on the occasion of death

Question:
The issue of the matter: we are in a state of life, and in it we have a threshold. If a person dies, they follow the degree, and likewise they prepare food for the family of the deceased, and they carry it out.

Answer:
The ruling on this is not permissible. It is not permissible for a Muslim to follow the funeral of a disbeliever. This is not permissible, and preparing food is not permissible.
On the occasion of deaths, as is done with feasts and celebrations, all of this is a religious innovation (bid'ah). What is done is preparing food for the family of the deceased because they are occupied with the calamity, so they help them by preparing food according to their need, giving it to them to eat during their days of grief. This is what the Prophet (peace and blessings be upon him) guided to. As for preparing more food than this and holding celebrations and many gatherings, where people gather from near and far, all of this is prohibited and not permissible. Yes.
As for following the funeral of a disbeliever, this is not permissible for a Muslim. Rather, if a disbeliever dies and he has no one among the disbelievers to bury him, then the Muslim buries him. If a disbeliever dies and he has no one among the disbelievers to bury him, he takes charge of his burial, and there is no harm in the Muslim burying him, because the Prophet (peace and blessings be upon him) ordered the burial of Abu Talib. He ordered Ali to bury Abu Talib and said: This is if he has no one to bury him, so that he is not left on the ground as a corpse to be buried.
