The condition which Islam lays down for permitting a man to have more than one wife is confidence on his part that he will be able to deal equitably with his two or more wives in the matter of food, drink, housing, clothing and expenses, as well as in the division of his time between them. Anyone who lacks the assurance that he will be able to fulfill all these obligations with justice and equality is prohibited by Allah (SWT) from marrying more than one woman.
