I have become a Muslim and try to practice Islam. However my mum is Christian and she says when she dies she wants to be cremated. I believe cremation is wrong in Islam because it affects the resurrection of the body. What do I do as I want to respect my mother’s wish to be cremated but I do not want to sin. What are the rules on cremation in Islam?

Cremation is wrong in Islam but it does not affect the resurrection. However, you are not obligated to fulfill her well.
