Among the conditions of appointing a proxy for the stoning of the pillars is that the principal must be in the state of ihram for Hajj
Machine translationRead the Arabic original
Q: I performed Hajj about two years ago and was unable to perform the stoning of the pillars due to the crowd, so my nephew, who was not a pilgrim, grew up and performed the stoning on my behalf. This action was also repeated in a previous Hajj about seven years ago,
so I hope you will issue a ruling on my action in this matter. May Allah guide you and make your knowledge beneficial?
A: The stoning of the pillars by a non-pilgrim (one who is not in the state of ihram) on behalf of a pilgrim is not valid; because it is a condition for the proxy that he be among the pilgrims. Therefore, the woman mentioned must offer a fidyah (ransom payment) in place of the stoning for each of the two Hajj pilgrimages, which is the slaughter of a sheep in Mecca that is acceptable as an 'Id sacrifice, and she should distribute it to the poor of the Haram, if she is unable to do so, then she must fast ten days for each fidyah.
