What is the Sharia view on zakat money collected to relieve a person's debt, when that did not happen: should it be given to him in full to benefit from, or distributed to other people in need? And is it permissible to take back part of the zakat money given to him if he is still among the poor?

The money collected for a man who is in debt, some of which is from zakat (definition): If the man is still a debtor (gharim (definition)) and eligible for zakat, then the money should be given to him to pay off his debt. Otherwise, it should not be given. If the creditor has absolved him, and the status of being a debtor is removed, then he should not be given from zakat, nor from pure donations, unless the donors intended charity for him. It is preferable to ask the donors about their intentions; if that is not possible, the money should be spent on a case similar to what it was collected for, or one that is more urgent. Zakat is disbursed to its rightful recipients among the debtors, the poor, and the needy. The man can be given from zakat under the description of destitution and poverty, as a person may combine several descriptions by which he becomes eligible for zakat, such as being poor and in debt.
