If your father is working in a interest based bank, his income is haram and also all the benefits he is getting from that bank.

As for exchanging his money with other money, this has no value and this is mocking Allah’s religion.

As for you mother’s hajj, she can go with this money and your father is the sinful one and his money is halal for you to use and haram for him to earn.

My father works in a bank and my mother wants to know if she performs haj with this income will her haj will also not be accepted , she doesn’t have money of her own and is dependent on my fathers savings.
