Can someone stone the Cemerat by proxy on behalf of another haci who is unable?

Stoning the Cemerat by proxy is permissible for those who have a genuine inability to perform the stoning themselves. This includes the sick, the very elderly who cannot walk to the Cemerat, pregnant women who would be endangered by the crowds, disabled hacilar who cannot reach the stoning area, and children whose guardians stone on their behalf. All four schools of jurisprudence permit this with minor differences in detail.

Sheikh Ibn Baz ruled that the proxy should first stone for themselves at each Jamarah, then stone for the person they represent. The sequence is: throw seven pebbles at the first Jamarah (al-Sughra) for yourself, then seven for the represented person; then move to the second Jamarah (al-Wusta) and do the same; then to Jamrat al-Aqabah (al-Kubra) and do the same. This way, the proxy completes all three Cemerat for themselves and then for the other person in the correct order.

Sheikh Ibn Uthaymeen emphasized that the proxy should only be appointed when the person is genuinely unable to stone — not merely for convenience. He noted that crowding alone is not a sufficient excuse for an able-bodied person, as crowding is the norm during Hac. However, he acknowledged that for women, the elderly, and those with medical conditions, the extreme crowding and potential danger at the Cemerat constitute a valid excuse. The Permanent Committee confirmed that the proxy must have already performed their own Hac obligations before representing another.
