The ruling for commissioning another to stone on one's behalf
Is it permissible for women, the ill and the weak to commission others to stone on their behalf?
It is permissible to stone on behalf of the weak, the ill and women. The basis for this is the permissibility of performing hajj on behalf of another; therefore commissioning another to stone on one's behalf is more of a priority. This is because hajj includes stoning as well as other rites. This commission is a dispensation for those who have an excuse preventing them from performing the rite themselves. For this reason, many scholars mentioned grounds other than those mentioned in the hadiths, by way of interpreting subsidiary questions in light of primary issues. These include those who fear for themselves, their property, or a caregiver.
It is permissible for the weak, the ill and women to commission others to stone on their behalf. There is no objection to this and they are not obliged to make expiation.
And God Almighty knows best.
