Stepping on the father as a way of treatment

Q 9: Some parents order their children to walk on them when they suffer from pain in the bones, or the back. We told them that it is not permissible for a child to walk on his parents on the floor, but the parents say that they accept this. Is this Mubah (permissible)?

A: There is no harm in a child walking on his parents so long as the purpose is to treat pain in their bones and backs, not to hurt them.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
