The conditions of the validity of throwing the pebbles

Q 3: My aunt performed Hajj last year. She told me that while she was throwing the pebbles she was not able to see the spot where those pebbles fell because of the over-crowdedness. She is not sure if all the pebbles fell into the Hawd (the pebble-throwing area) or not, taking into consideration that she sometimes was able to see some of them. What should she do in this case? Kindly clarify this issue for us. May Allah reward you with the best.

A 3: One of the conditions for the validity of throwing the pebbles (at the pebble-throwing area during Hajj) is making sure that the pebbles fall in the pebble-throwing enclosure. So, if she is sure that she saw those pebbles fall into the Hawd, and later she had doubt about the pebbles' not falling in the enclosure of the pebble throwing, her throwing is valid and she simple dismiss that doubt. But if she was doubtful and was not sure of the falling of the pebbles in that enclosure at the time of throwing, then she has to offer a Fidyah (ransom) which should be slaughtered and distributed among the poor of Al-Haram. However, if she can not afford offering a Fidyah, then she has to fast ten days.May Allah grant us success. May Peace and Blessings of Allah be upon our Prophet Muhammad, his family and his Companions!
