If someone stole money from him that was designated for charity?

If the charity is stolen from the donor before he hands it over, he is not obligated to replace it. However, if the money belongs to someone else, the trustee is not liable for what is damaged while in his possession unless he exceeds his authority or is negligent. If he exceeds his authority or steals the money, then he is liable. As for stealing with the intention of giving charity, it is forbidden, and a person is not permitted to commit a sin to achieve a reward.
