Debased coin (nabahraja)

النَّبَهْرَجَة (الدراهم المغشوشة)

In the usage of the Hanafis, nabahraja is a worthless or counterfeit dirham, or one that traders reject, or one struck outside the ruler's mint. If silver predominates it is treated as pure coin, and dealing in it is allowed even when its alloy is unknown; some jurists require zakat on it. If the alloy predominates, its value is assessed if it circulates or is held for trade, and zakat is due if that value reaches the nisab; otherwise, and unless its silver alone reaches the silver nisab, no zakat is due. Good coin may not be exchanged for it except equal for equal. The entry refers the detail to the entry on counterfeit coin (zuyuf). ^{1 2}
