Investors or subscribers are typically responsible for paying Zakat on their investment units within funds. However, if the fund's terms and conditions stipulate that the fund manager will handle Zakat payments on behalf of the investors, then the investor can rely on the fund manager to fulfill this obligation. It's important to note that not all investment funds on Aseel's platform have the fund manager handle Zakat payments for investors. Therefore, users of Aseel's platform must take full responsibility for calculating and paying their Zakat.
