The ruling on one who leaves off the stoning of the small pillar, and the ruling on a wife delegating her husband to stone the pillars

Question:
This questioner, Muhammad, is Egyptian and resides in the Kingdom. He says: I performed the obligatory Hajj with my wife last year, and we performed all the rituals, including the arrival tawaf, sa'y, the tawaf of farewell, standing at 'Arafah, staying overnight at Muzdalifah, and staying overnight in Mina during the days of Tashriq. I delegated my wife to me for the stoning of the pillars. On the day of 'Id, I stoned the large pillar with seven pebbles for myself and seven for my wife. During the days of Tashriq, I stoned the large pillar again with seven pebbles for myself and seven for my wife. On the second day of Tashriq, I stoned the middle and the small pillar, each with seven pebbles for myself and seven for my wife. So the total number of pebbles I stoned for myself and my delegate was fifty-six. I learned during these days that what I did was not valid. Please inform me: Do I have to repeat my Hajj? Is our Hajj valid? And do we have to pay a fidyah (ransom payment)? May Allah reward you.

Answer:
Your Hajj is valid, if Allah wills, if the only deficiency that occurred was what you mentioned, which is the neglect of stoning the pillars, because you started with the middle one and then stoned the one after it, and did not stone the small one. Thus, you left off one of the three pillars for yourself and for your wife. In this case, there is a fidyah (ransom payment) for you and one for her. You slaughter two fidyah (ransom payments) in Makkah and distribute them among the poor of the Haram as compensation for this obligatory duty that you left off. Delegating your wife to you, if it was due to her inability or fear for her safety from the crowd and danger, is valid, if Allah wills. Yes. May Allah bless you.
