Zakah to my father in law

Mufti,

My father in law had a good job at a reputable company, for which he worked for for over 3 decades.

However, about 9 years back that company went bankrupt, and they paid my father in law out. My father in law used that money and all his savings to start a business. However, that business became a disaster, and ny father in laws was not making any profit. Rather, he was in a deficit each month. Since there were contracts in place, he soon had to sell his assets to cover his expenses. He soon lost everything.

Currently he gets a mere R10 000 every month, which just covers all his expenses. He has no savings, investments etc. In fact, he has nothing to his name at all.

Can I give him my Zakah?
