Is there sin in bank money spent on the family, or is their illness and lack of money a trial from Allah, knowing that they pay zakat and give charity? And what should they do if it is a sin?

Usury is a danger to the individual and society, and it is deprived of blessing, and it may be a cause of calamities and losses. It is not permissible to deposit money in usurious banks, and it must be withdrawn, and one must repent from usury, and dispose of the usurious interest by spending it on the interests of Muslims or in charity. Look for a legitimate alternative for preserving and growing money, such as Islamic banks. Whoever fears Allah, He will protect him, and whoever relies on Him, He will suffice him. The usurious interest exceeding the principal may not be utilized except in cases of extreme necessity. Dreams do not form the basis of religious rulings, and they may be from Satan to trivialize the sin of usury.
