105 common mithqāls. Therefore, if silver reaches 105 mithqāls and the other conditions that were mentioned are fulfilled, one must give one-fortieth [2.5%] – which is equivalent to two mithqāls and fifteen nukhuds – as zakat. As long as silver does not reach this amount, zakat is not obligatory on it. 2.
Twenty-one mithqāls, meaning that if twenty-one mithqāls are added to 105 mithqāls, one must give zakat on the entire 126 mithqāls in a manner that was previously mentioned; and if less than twenty-one mithqāls are added, he must give zakat on only 105 mithqāls [which was the first niṣāb mentioned above], and the extra is not liable for zakat.
The same applies to every other addition, meaning that if twenty-one mithqāls are added, one must give zakat on the entire amount; and if less than twenty-one mithqāls are added, the added amount is not liable for zakat. If a person doubts whether or not silver has reached the niṣāb, then based on obligatory precaution, he must investigate further.
