Mumbai (Maharashtra) [India], April 18 (ANI/PNN): Zakat is one of the five pillars of Islam along with the other forms of Worship, like Salah (prayer) and Sawm (fasting). Its fundamental importance lies in the fact that it fosters the quality of sacrifice and social equity. It is a mandatory charity that Muslims are obliged to pay if their wealth rises above a threshold limit after deducting all their living expenses and liabilities.
