Zakah on wealth the majority of which is forbidden

Question:
Honorable Shaykh. If the majority of a person's wealth is forbidden (haram) and it has reached the nisab (minimum threshold) and a lunar year has passed over it, is there zakah on it? And what is the ruling if all of the wealth is forbidden?

Answer:
This is invalid and cannot be owned. Zakah is only obligatory in what is owned, and this is not owned by anyone. This is invalid. The ruling is that if its owner repents, he repents to Allah and does not use it. Rather, he disposes of it and places it in a public project, to be used for lost wealth that has no owner. He places it in a public project from which people benefit, and he does not use it after repenting. He does not use the forbidden, nor does he keep it in his library, and there is no zakah on it because it has no owner. And Allah the Exalted knows best, and may Allah send prayers and peace upon our Prophet Muhammad.
