Fasting in place of the sacrificial animal for children in the case of tamattu'

Question:
All right, we will limit ourselves to this, Honorable Shaykh, from the questions we have received. Abu 'Ali says: A person performed Hajj as a mutamatti' along with his three young children, but he was unable to slaughter the hady for the children due to financial constraints. Is he obligated to fast on their behalf, or is he not required to do anything regarding the children because they are not yet accountable?

Answer:
Fasting is necessary. If they are able to fast, they fast for themselves. If they are unable to fast because of their young age, it is obligatory for you to fast on their behalf, because you are the one who intended ihram for them, and you are the one who brought them into the state of ihram. Therefore, you must adhere to the requirements of ihram. Among these requirements is that the one who does not find the hady for tamattu' fasts for ten days. So, you fast ten days for each one of them. Yes.
