Question
A person vowed to sacrifice for a large number of people, but he was unable to fulfill the vow. Is it permissible for him to sacrifice on behalf of the Prophet (peace be upon him)?
Answer
I say, and with God's help: What he has vowed as a vow remains a debt upon him until the time of ability, and it is different from the sacrifice of the Messenger of God, peace be upon him, and God knows best.
