Question:
I became Muslim about 4 years ago. I got married to a muslim man, I entered the marriage with money from my previous marriage. I know I must pay zakat on this money. My new husband does have some previous debts to pay, My question is can I give him the zakat money to pay his debts?
Answer by Dr. Hatem Al-Haj
All praise be to Allah, and may his peace and blessings be on the last and best prophet and messenger, Muhammad.
Congratulations on becoming a Muslim. Such is the happiest and greatest event in one`s life.
Yes, you may give your indebted husband from your zakat money.
May Allah grant us and you strength in the religion.
Allah knows best.
