Is it permissible for a young man from the Household of the Prophet (peace and blessings be upon him) to study at a university funded by charity and donations, some of which come from usurious or unknown sources? And does this fall under the ruling of building a mosque with the sadaqat (charitable donations) of the Companions? And is it permissible for him to benefit from scholarships offered, whether due to inability to pay or for academic excellence? And is it permissible to take them with the intention of repaying them as a debt? And what is the ruling on grants offered by foreign countries?

What the questioner mentioned has no relation to charity (sadaqah (definition)), because sadaqah is an act of transferring ownership for the sake of drawing closer to Allah, and studying in these universities does not involve transferring ownership, nor is it for the sake of drawing closer to Allah. No scholar is known to have prohibited the Prophet's household (Ahl al-Bayt) from benefiting from public facilities built from donations. There is no harm for any member of the Prophet's household in benefiting from a discount on tuition fees, because it is not from charity, but rather a reduction in the cost.
