My wife has founding shares in a bank and has been receiving small profits. She did not calculate zakat precisely, but would occasionally give charity. Now, she wants to know the Islamic ruling on what she must pay. What should she do?

Praise be to Allah, if the wife is a shareholder in an interest-based bank, this is forbidden, and she must repent and withdraw the shares because the work of interest-based banks is based on lending and borrowing with interest. The profits exceeding the capital must be disposed of by spending them on the general interests of Muslims. However, contributing to an Islamic bank is permissible, and zakat is due on the capital and profit if it reaches the nisab and a year has passed on it. 2.5% must be given out of the total after deducting the portion of the share allocated to fixed assets. Previous charities do not count towards the obligatory zakat because the intention of zakat is essential.
