Dinar Calculator for PC

The present application before you (Shariah Dinar Calculator) meets the needs of those who are responsible for applying the jurisprudential issues related to the dinar.
Let us mention some resources that the person in charge needs to know the value of the dinar, which are:
The first resource: In Zakat, scholars mention the conditions for the obligation of Zakat, including reaching the threshold. In the Zakat of gold, they mention that the first threshold is twenty dinars, and the second threshold is four dinars, after the twenty dinars.
The second resource: In Khums, scholars mention the obligation of Khums in metal if it reaches the threshold, which is twenty dinars.
The third resource: In Diya (blood money), scholars mention that one of the options for the complete Diya is a thousand dinars, and the Diya of crimes varies according to the crime. Let us mention this issue, which is a very common issue:
(Fatwa No. 376): For causing redness in the face by slapping, the compensation is one and a half dinars; for causing greenness, three dinars; and for causing blackness, six dinars. If these things occur on the body, the compensation is half of what it would be for the face."
The source is Talkhimat Minhaj al-Salihin by Grand Ayatollah Sayyid Abu al-Qasim al-Khoei (may his secret be sanctified).
Thus, the need arose to know the weight and price of the dinar to apply various Shariah issues.
Therefore, we programmed this application to cover the gap in this field and meet the needs of believers.
