more or less mr.nazrul islam is correct regarding to four marriages of muslims (as i have more muslims friends than hindus & in my fair knowledge i haven't noticed more than one wife of any of my friends & their fathers.even in some backward hindus i have seen more than one wife) & nos of children (this is the case with poor & uneducated muslims having more than three children & same problems is with poor & lower caste hindus).
