Question: Is it permissible for a person to appoint a proxy to stone the pillars on his behalf if he is capable of doing so himself?
Answer: It is not permissible for a capable person to appoint a proxy; each person must stone the pillars for himself, except for a child, a disabled person, a sick person, and a pregnant woman. The guardian of a child stones on his behalf, and likewise the proxy of a disabled person due to old age or illness, and likewise the proxy of a pregnant woman or a woman with children for whom there is no one to look after them.
