Is blood money or expiation (fasting for two months or feeding the poor) obligatory for someone who caused the death of their grandmother due to mistreatment of a fractured pelvis by a traditional healer?

No blood money (Diyyah) or expiation (Kaffarah) is required of you for bringing the popular healer who caused your grandmother's death. Instead, what is required is repentance for this action, because the one responsible for the death is the healer. The cause of death must be determined through a hospital report. If the death was due to him, then he bears the responsibility, provided he was not skilled, or was transgressing, or was negligent. Otherwise, he is not liable.
