PowerPoint Presentation: Islam prescribes a system of Zakat (obligatory annual charity). Islamic law prescribes that every person who has a saving that exceeds the nisab level i.e. more than 85 grams of gold, should give 2.5% of that saving every lunar year in charity. If every rich person in the world gave Zakat sincerely, poverty will be eradicated from this world. Not a single human being would die of hunger.
