The ruling on completing Hajj on behalf of a child who did not complete the tawaf of ifadhah

Question:
Honorable Shaykh, may Allah grant you success. He says: Many years ago, I performed Hajj with two children with me. Then, due to the severe crowding during the tawaf of ifadhah, I feared for the two small children, who were only months old. He says: I did not complete the tawaf of ifadhah with them, and their Hajj was not completed, even though I had entered ihram for them for Hajj. Is there anything required of me now? And what should I do?

Answer:
Yes, it is obligatory to complete the Hajj. You go with them and complete the Hajj. If the tawaf of ifadhah and the sa'y remain for them, you go with them now, and you perform tawaf with them and sa'y with them, and their Hajj will be completed, if Allah wills. Yes.
