What is the ruling on repeated oaths not to drink from the money of national sukuk, and what should the questioner do with her family who have not responded to withdrawing their money from these sukuk?

First: Whoever wishes to engage in a transaction must know its ruling. There is no blame upon one who relies on the fatwa (definition) of trustworthy scholars permitting it. However, if its prohibition becomes clear to someone, they must withdraw from it.

Second: If it is not clear to your family that it is prohibited, they are not obliged to dispose of it, especially if they relied on a fatwa permitting it.

Third: You are permitted to eat and benefit from what your family provides, because wealth that is unlawful in its earning is only unlawful for the earner. If you swore not to benefit from the profits generated by these sukuk (definition), you may either uphold your oath or expiate it with a single expiation.
