Zakah is payable on money including banknotes, coins, and the like, and commercial commodities
The Zakah is due on money including banknotes, coins, commercial commodities, and the like when it reaches the Nisab (the minimum amount on which Zakah is due) independently; or when other parts of property on which Zakah is due is added after the passing of a Hawl.
The debt does not prevent the obligation of Zakah. May Allah grant us success. May Allah's Peace and Blessings be upon Prophet Muhammad, his family and Companions!
