Zakah should be paid from both the capital and its profits
A:
The Zakah is due on the money that you possess and on its profit after the passage of the Hawl on the capital while it is a Nisab (the minimum amount on which Zakah is due) or more (Part No. 8; Page No. 329) and regardless the sales are on installment or not.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
