His wife deputized him to throw the pebbles on her behalf. However, He could not fight his way through the huge crowd

Q: In 1414 A. H., my wife and I performed Hajj, and on the 12th of Dhul-Hijjah, my wife authorized me to throw the pebbles (at the stone pillars during Hajj) on her behalf. However, I could not fight my way through the huge crowd and so could not throw Al-Jamrah Al-Wusta (second or middle pebble-throwing area) and Al-Jamrah Al-Kubra (largest pebble-throwing area; Jamarat-ul-`Aqabah). I only managed to throw Al-Jamrah Al-Sughra (first or smallest pebble-throwing area). Afterwards, I returned to the tent as my companions would not wait for me. On my way to the tent, I met an Egyptian whom I do not know and I told him what had happened, so he offered to throw the pebbles at the Jamarat on behalf of me and my wife. What is the ruling on this throwing, and what should I and my wife do? (Part No. 10; Page No. 328

A: The questioner should offer a Fidyah (ransom) in Makkah, which is slaughtering a sheep meeting the same conditions for Ud-hiyah (sacrificial animal offered by non-pilgrims), or one-seventh of Badanah (a camel or a cow or an ox driven by pilgrims to be offered as sacrifice within the sacred precincts of Makkah) and should distribute its meat among the poor in Makkah. This is to make up for the throwing of pebbles which he and his wife abandoned. His wife should also offer a Fidyah. If they could not offer a Fidyah, they should fast for ten days.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
