Question: Is it allowed for my husband to pay the Zakaah on my wealth on my behalf, given that he is the one who gave me the wealth? Is it allowable to give the Zakaah to my nephew, whose wife passed away and he is a young man who is thinking about getting married?
Response: Zakaah is obligatory upon your wealth, if you have the nisab or more of gold, silver or other forms of Zakaatable wealth. If your husband, with your permission, pays it for you there is no harm. The same is true if your father, brother or others, with your permission, pay it on your behalf. It is allowed for you to pay the Zakaah to your nephew to help him get married if he not able to support himself.
Shaykh Ibn Baaz
