Palm reading is usually judged by what it claims to do. A theatrical personality reading at a fair is treated differently from a serious claim that your future, marriage, death, wealth, or spiritual condition can be read from skin creases.
Christianity commonly objects to palm reading as divination. Islam more directly prohibits fortune-telling and claims to know the unseen. Hindu-linked traditions are more varied because palmistry has historical roots in Indian interpretive systems.
So the clean answer is this: if palm reading is used as fortune-telling or spiritual authority, many religions treat it as sinful, forbidden, or spiritually dangerous. If it is used as entertainment, the ruling depends on the tradition and the seriousness attached to it.
