Is the 2.5% rate the fixed Zakat rate everywhere? Does it change with the country and currency? Is one sinful if their Zakat is unintentionally short? How is Zakat calculated for a loan due in a later year? Is the method of continuous Zakat calculation correct? To which relatives is Zakat permissible? Is it permissible to give Zakat to a sister who is not poor?

The obligatory Zakat (definition) rate is a fixed 2.5%, and one must endeavor to pay the Zakat for past years as much as possible. A debt owed by a solvent person is subject to Zakat for every year. However, a debt owed by an insolvent or procrastinating person is subject to Zakat for one year only upon its recovery. The example provided for calculating Zakat is correct. It is permissible to give Zakat to needy relatives who are not dependants. If the sister needs dental treatment and cannot afford it, and her father, despite his ability, refuses to pay for it, then there is no objection to giving her from the Zakat.
