What is obligatory upon a woman who left off the stoning of the pillars while she was able to do it?

Question: A woman asks and says: I performed the obligatory Hajj five years ago, but I did not stone the pillars except on the first occasion. That is, I stoned on the night of the festival before dawn, because we left Muzdalifah after midnight out of fear of the crowd. Then I threw the pebbles, but I do not know whether they fell into the pit or missed it and did not fall in. At that time, the crowd was very heavy, and I was ignorant at that time that it is obligatory for the pebbles to fall into the pit. Also, I did not stone on the second and third days, but I appointed my brother to stone on my behalf, and that was only out of fear of the crowd. I was also ignorant that it is obligatory for a woman to stone with her own hand and not appoint someone else except if she is unable to do so. Please inform me of what is obligatory upon me regarding my stoning of the pebbles when I did not know whether they were falling into the pit or missing it, and what is obligatory upon me regarding my appointment of my brother to stone on the second and third days? Is a fidyah obligatory upon me, or what? May Allah reward you with good.

Answer: You owe one sacrificial animal for all of that: for leaving off the stoning on the second and third days while you were able to do it, and for the stoning on the first day where you doubted whether the pebbles reached the pit or not. The point is that you owe one blood offering, which is a sacrificial animal, a one-year-old sheep or a two-year-old goat, like the 'Id sacrifice. It is to be slaughtered in Makkah for the poor, on account of leaving off this obligatory duty; because it is necessary to know that the pebbles fell in the target, or to have a strong presumption that they did.
