Q: What is the Nisab in grams?
A: • The gold Nisab is 87.48 grams.
• The silver Nisab is 612.36 grams.
The above Nisab conversions are based on the Hanafi school. Other schools have a gold Nisab of 85 grams and 595 grams of silver.
The unit of mass used at the time of the Prophet was different to what is used today. Therefore, scholars converted different units of mass across time keeping the benchmark 20 Dinar of gold and 200 Dirham of silver. Hence, due to the multiple conversions and juristic differences in understanding some weight and volumetric measurements, scholars have slightly different Nisab standards.
A famous opinion of the conversion rates of Dinar and Dirham is :
1 Dinar = 4.374 grams
1 dirham =3.0618 grams
20 Dinar = 87.48 grams
200 Dirhams = 612.36 grams
And Allah knows best!
