What is the ruling on a founder of a charity employing unqualified teachers in an Islamic school affiliated with the charity and paying their salaries from donation funds, simply because they are his acquaintances?

The overseer of donations is entrusted with them, and it is not permissible for him to disburse them except as necessitated by public interest, without favoritism, because it is the money of others. Accordingly, if the close employees are not qualified and their employment is not necessitated by public interest, then it is not permissible for him to employ them with donation funds merely due to kinship. He is sinful and liable for whatever was disbursed unlawfully. For an agent has no authority to act except as permitted by his principal, and if he exceeds or neglects the funds, he is liable for whatever is lost from them.
