The second question in the letter of the brother Abdul Salam, in which he says:

The second question in the letter of the brother Abdul Salam, in which he says: Is it valid for a person who has not performed Hajj for himself to perform Hajj on behalf of another person who has a debt upon him, knowing that the one who will perform Hajj on behalf of the debtor has already secured a guarantee for the debt he owes? Is this valid? Please issue a ruling for us, may you be rewarded, and may Allah reward you with the best reward for us.
Answer: A person is not permitted to perform Hajj on behalf of another before he has performed Hajj for himself; this is the correct view among the scholars. However, he should start with himself and perform Hajj for himself, and after that, there is no harm in performing Hajj on behalf of another if he intends good by it, wishes to participate in the Hajj and the great sacred sites, and wants to share in the good with the Muslims. He may take money to help him perform Hajj on behalf of another, and there is nothing wrong with that, but he must start with himself; he must perform Hajj first. Once he has performed Hajj first, there is nothing wrong with performing Hajj on behalf of another. If he performs Hajj for himself, that is more appropriate and better, unless he takes money to perform Hajj on behalf of another with a good intention, such as the intention of fulfilling the right owed by his brother in the form of Hajj, or the intention of participating in the good and being eager to reach the sacred sites when he is unable to do so, in which case he seeks assistance by taking money to perform Hajj on behalf of another so that he may share in the good with him. This is a righteous deed. Yes.
