Salam Alaikom
My father is trying to purchase a home but by misleading the bank by faking his income and getting approved for the mortgage. We have tried to stop him but he wont listen and he is also pressuring and forcing my mother to co-sign with him on the fake documents because otherwise he won’t be successful. Me and my family have no source of income other than my father and we are relient on him. Will it be haram for us to live in that home and will our usage of the land for praying, wudhu, ghusl, etc be accepted or is it all unlawful and void? If it’s unlawful, what can we do in this situation?
