Wisdom behind the permissibility of polygamy

Question 3: Why does Islaam permit polygamy, i.e. That a man may marry two, three, or four wives at the same time. What are the conditions, characteristics, and advantages of such permissibility? How can we refute the allegations of those who doubt the permissibility of polygamy?

Answer: It is Allaah (Exalted be He) Who makes it Mubaah (permissible) for a Muslim to marry up to four wives if he is able to fulfill their rights, is sure that he can do justice between them, and does not fear of being unjust. Thus Allaah (Exalted be He) revealed to His Messenger (peace be upon him): And if you fear that you shall not be able to deal justly with the orphan-girls then marry (other) women of your choice, two or three, or four; but if you fear that you shall not be able to deal justly (with them), then only one or (the slaves) that your right hands possess.

Question 1: Why did the Messenger of Allaah (may peace and blessings be upon him) have more than one wife?

Answer: With Allaah is the Perfect Wisdom. It is His Wisdom that He (Glorified be He) madpolygamye it Mubaah (permissible) for men to marry more than one wife, whether in the previous Sharee`ahs (Divine laws) or in the Sharee`ah (Islaamic law) that was revealed to our Prophet Muhammad (peace be upon him). Polygamy was not thus peculiar to our Prophet (peace be upon him). Rather, Ya`qoob (Jacob, peace be upon him) had two wives. Also, Sulaymaan (Solomon, peace be upon him) married ninety nine wives at the same time, and he had sexual intercourse with all of them on the same night hoping that Allaah would grant him a son from each one of his wives that would fight for the cause of Allaah… read more here.
