Is it permissible to appoint a proxy for tawaf and sa'y?

Question : You are right, O 'Abd al-Latif. Welcome, my brother Fathi, calling from Riyadh. Yes, from Riyadh. May Allah welcome you. Regarding tawaf and sa'y, is it permissible to appoint a proxy for them?

Answer : It is not permissible for a person to appoint another to perform tawaf and sa'y on his behalf, based on the saying of Allah the Exalted: Accordingly, if a person is unable to perform tawaf and sa'y himself, he is carried during tawaf and sa'y, and he performs sa'y on a camel. Umm Salimah (may Allah be pleased with her) complained to the Messenger of Allah (peace and blessings be upon him) regarding the tawaf of departure, that is, the farewell tawaf, saying that she was ill. He told her: "Perform tawaf behind the people while you are riding." He did not permit her to appoint another in her place to perform it on her behalf.
Likewise, for all the acts of Hajj, it is not permissible for a person to appoint another to perform them on his behalf; rather, it is obligatory for him to perform them himself. Even for stoning the pillars, it is obligatory for a person to stone them himself and not appoint another. However, if he is unable to reach the pillars, he is excused and may appoint another. But if he is able, it is obligatory for him to stone them himself. If it is not feasible for him to stone them during the day, he stones them at night. If it is difficult for a person to walk in the sun after the sun passes its zenith during the days of Tashriq, he may postpone the stoning to the night so that he can stone them himself, and it is not permissible for him to delegate it to another.
