Does the lack of blessing in money, children, and one's spouse stem from the husband's dealings with usurious banks, and what is the solution to this problem?

The decrease of blessings (baraka) in wealth, children, and all other life matters is caused by sins and transgressions, whereas piety and obedience to Allah are causes for good to prevail and for the blessings of the heavens and the earth to be opened. The sins of parents affect the corruption and disobedience of their children. Bank interest is forbidden usury (riba), and those who deal with it must repent and withdraw their money, getting rid of the interest by spending it on charitable causes.
