Is one who continues in a line of work that has been shown to be forbidden, in order to liquidate the business in a way that guarantees the preservation of rights, sinful, and is the compensation he receives during this period lawful or unlawful?

There is no harm in continuing with work that does not assist in usurious financing. However, work that assists in usurious financing for purchasing goods is not permissible, and one must cease it immediately.

Money earned from such work is forbidden and must not be paid as salaries to employees. Instead, it must be disposed of by spending it on the welfare of Muslims, such as the poor and needy, and building hospitals.

"And whoever fears Allah - He will make for him a way out And will provide for him from where he does not expect." And whoever abandons something out of fear of Allah, Allah will compensate him with something better.
