Prophets had numerous wives as is known. This is not specific to just Islamic texts.

However, from the inventions the Christians made to the Religion of God was their forbidding polygynous marriages – and that was not from the Laws of Allāh – they changed the Law. So the Christian has only one wife. So in these types of societies, they have no real problem and do not mind a man (even a married man) having girlfriends and partners and living with whomever they please in a manner that is prohibited by Allāh. So they will allow this whilst prohibiting plural marriages! Those who speak ill of plural marriages (polygyny) are affected by the modern-day Christian ideology (which itself is not the way of the Prophets as mentioned in biblical scriptures). So some Muslims speak with the arguments of the Christians claiming that polygyny is oppressive towards women. This is not the case in reality at all! It is not unjust upon women. Rather there is in it justice for women and goodness. If a man transgresses against any of his wives then he is reprimanded for his transgressions. Allāh, the Majestic and Most High, has obligated justice: “And if you fear that you will not deal justly with the orphan girls, then marry those that please you of other women, two or three or four. But if you fear that you will not be just, then marry only one..” [An-Nisā 4:3] The the plural marriage is allowed only for the one who can establish and maintain justice between his wives. As for the one who is not able to maintain the required justice then he is prohibited from plural marriage so that he is prevented from oppression, transgression and tyranny. ___________
