Children whose father left them a house that he built with usury: do they have the right to benefit from any of it?

The questioner : The Shaykh says:The questioner : That there are children whose father left them a house that he built with usury: do they have the right to benefit from any of it?

The Shaykh : Yes, wealth that is transferred through a lawful means, which here is inheritance, is lawful, except in one case. It is lawful because the sin is upon the deceased and none of his sin attaches to the heirs, unless they were partners with him or helped him in this forbidden earnings. I said except in one case: if the heirs know that there is a right belonging to some people in this wealth, such as a debt, then they must deliver this debt to its owners. Then whatever remains, even if the means of earning it was forbidden as we said, it is lawful for them.
