If the matter is as you describe, and your sister’s husband is in debt and he cannot pay it off, then it is better for you to pay off his debts with what you have, and delay taking your sister for Hajj, because paying off her husband’s debts and relieving the hardship of both of them is more important than taking her for Hajj, and is more beneficial for both of them. She is not obliged to do Hajj until she can afford it.
And Allaah is the Source of strength. May Allaah send blessings and peace upon our Prophet Muhammad and his family and companions. End quote.
