Polygyny in Islam

"If you fear that you cannot treat orphans with fairness, then you may marry other women who seem good to you: two, three, or four. But if you fear that you cannot maintain equality among them, marry one only or any slave-girls you may own. This will make it easier for you to avoid injustice"

"Quran (4:129) - "Ye are never able to be fair and just as between women, even if it is your ardent desire"

"A man should marry four wives: A Persian to have some one to talk to; a Khurasani woman for his housework; a Hindu for nursing his children; a woman from Mawaraun nahr, or Transoxiana, to have some one to whip as a warning to the other three."

"Many Westerners forget that when the Prophet spoke of four wives as the maximum allowable number, he had in mind a reduction to four as compared to the number then often prevailing; moreover, Mohammed specified that a man should acquire more than one wife only if he could treat them all with equal justice — obviously a difficult feat for even the most diligent man to achieve. In effect, then, the Prophet curtailed the number of wives."

"In my Ummah, he is the best who has the larg­est number of wives­."

"And if ye fear that ye will not deal fairly by the orphans, marry of the women, who seem good to you, two or three or four; and if ye fear that ye cannot do justice (to so many) then one (only) or (the captives) that your right hands possess. Thus it is more likely that ye will not do injustice"

"But if ye cannot do justice between orphans, then marry what seems good to you of women, by twos, or threes, or fours: and if ye fear that ye cannot he equitable, then only one, or what your right hand possesses " (i.e. female slaves)"."
