Must a woman repeat Hajj if she deputized her husband to stone the Jamarat due to the crowd, and then later felt guilty?

The Hajj is valid and does not need to be repeated. It is permissible to delegate the throwing of the pebbles (rami) due to overcrowding or fear for one's life or honor, provided the excuse persists throughout the entire time for throwing. One who fears overcrowding can throw the pebbles at night or on the following day of the Days of Tashreeq if the crowd is less, but one should not be lax in throwing merely out of fear of overcrowding. The Shafi'is and Hanbalis hold that whoever misses throwing the pebbles for one or two days, whether intentionally or forgetfully, can make it up during the remaining Days of Tashreeq, and no sacrifice (dam) is due. The Hanafis believe that whoever throws the pebbles at night has fulfilled the requirement, and no sacrifice (dam) is due, and this is the preferred view if the delay is due to an excuse. The Malikis stipulate a sacrifice (dam) for one who delays the throwing beyond sunset, and similarly the Hanafis if it is delayed until the next day. Texts supporting these different opinions have been reported.
