Is Zakat given to pay off a usurious loan taken to purchase a house?

It is forbidden to engage in usurious transactions, whether lending or borrowing. If a person incurs debt in a forbidden matter, such as usury, they should not be given from Zakat unless they repent, show remorse, and resolve not to return to it. This is because giving them Zakat before repentance would be considered aiding in sin. If they do not repent, they might resort to borrowing with usury again.
