If she authorized someone to throw the pebbles at Jamarat on her behalf, for fear of crowdedness

Q 1: A woman who once performed Hajj asks: I did not throw pebbles at Jamarat (stone pillars marking the pebble-throwing areas, Jamarat-ul-`Aqabah being the closest to Makkah), as my brother did that on my behalf and did not allow me to accompany him for fear that the crowds may harm me. Is there any shortfall in my Hajj, bearing in mind that I performed it many years ago?

A: If the woman in question was unable to throw the pebbles at the Jamarat on her own or feared for her safety due to the crowds and appointed her brother to do that on her behalf, then there is nothing wrong with that.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
