Almost a quarter of the world's population are giving money, charity, alms and undertaking huge philanthropy inspired by their Muslim faith. Some estimates put the value of this giving at around $1 trillion a year, though exact figures are impossible to know. Yet if Muslim giving is so generous in spirit and so massive in scale, why are these numbers just estimates? Where is the research data? Why, to the best of my knowledge, is there no specific study to confirm these estimates? Where is the data that records the social impact of this giving?
