An elderly or disabled haci who is genuinely unable to reach the Cemerat — due to physical inability, severe illness, or the risk of serious harm from the extreme crowding — may appoint a proxy to stone on their behalf. This is permitted by all four schools of jurisprudence and is a well-established concession based on the principle that Allah does not burden a soul beyond its capacity.
Sheikh Ibn Baz stated that the proxy should first stone for themselves at each Jamrah, then stone for the elderly person at the same Jamrah, before moving to the next Jamrah. This means at Jamrat al-Sughra, the proxy throws seven pebbles for himself, then seven for the elderly person, then moves to Jamrat al-Wusta and repeats the process, and finally at Jamrat al-Aqabah. He also permitted the proxy to complete all their own stoning at all three Cemerat first, then repeat the circuit for the elderly person, though the first method is preferred.
Sheikh Ibn Uthaymeen clarified that the concession for proxy stoning is for genuine inability, not mere inconvenience. A person who can reach the Cemerat — even with difficulty — should stone for themselves, using a wheelchair or with assistance if needed. Proxy stoning is for those who truly cannot be present, such as a bedridden haci or one whose condition would genuinely deteriorate from the journey to the Cemerat. Women who fear the extreme crowding may also appoint a proxy.
