Is it permissible for a woman to perform Hajj using her salary while she is paying off an usurious loan? And what is the ruling on her Hajj in this situation?

Borrowing with interest (riba) is forbidden. Whoever is afflicted by it must repent and repay the loan quickly. They are only obligated to repay the principal amount. As for the interest, it should only be paid if there is a fear of harm. A woman may perform Hajj using her salary if it is permissible. If her debt is in installments and traveling for Hajj would affect the repayment of these installments, then Hajj is not obligatory for her until the debt is paid off. However, if her travel does not affect it, then there is no harm for her in performing Hajj. It is preferable, if Hajj is supererogatory and she has already performed Hajj, that she repay the debt to free herself from the forbidden riba.
