Zakaat on mortgaged jewelry
The person mortgaging jewelry gives their possession to the mortgagee. The mortgager can’t draw benefit from that jewelry. For this reason, the Jurists have clarified that Zakaat is not Compulsory on mortgaged wealth.
Thus, the Zakaat of mortgaged jewelry is not Compulsory, neither on the mortgagor nor on the mortgagee. As mentioned by ‘Allama Ibn Nujaim Misri (May Allah shower His mercy on him), Vol. 1, Pg. No. 355.
