Agency in stoning the pillars for a woman with children

Question: I performed Hajj last year, praise be to Allah, and I stoned the pillars on behalf of my wife. She was not pregnant or ill, and we had four small children with us. I saw the crowd and did not see her able to stone the pillars. Is agency permissible, or did she leave an obligatory duty? What is required of her now?

Answer: If the situation is as you described, she owes nothing if she appointed you as her agent in that matter; because her performing the stoning while with the children involves great danger to her and to the children.
