Is it permissible to give Zakat al-Mal to one's daughter's husband to pay off a debt he owes, given that he has recently graduated and is currently unable to pay off his debt?

It is permissible to give zakat (definition) to the gharim (definition) (debtor), who is someone in debt. This category is divided into a debtor for his own benefit or for the benefit of society. For a debtor for his own benefit, it is stipulated that he must be in need to repay his debt. His ownership of a dwelling or clothing, etc., does not prevent him from receiving zakat, provided that he is not wealthy and capable of repayment, and that his debt is for a permissible matter or an act of obedience. It is permissible to give zakat to a son-in-law if he is among the debtors.
