ARGUMENTS POSED IN DEFENSE OF ISLAM:
Polygamy means a system of marriage whereby one person has more than one spouse.
Polygamy can be of two types. One is polygyny where a man marries more than one woman, and the other is polyandry, where a woman marries more than one man. In Islam, limited polygyny (up till four wives) is permitted; whereas polyandry is completely prohibited.
RESPONSE:
I agree with your definitions.
ARGUMENTS:
”Qur’an is the only religion on the face of the earth that allows men having up till four wives, Allah says in the Holy Qur'an:
"Marry 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." Al-Qur’an (4:3)
Before the Qur’an was revealed, there was no upper limit for "polygyny" and many men had many wives, some even hundreds. Islam put an upper limit of four wives. Islam gives a man permission to marry two, three or four women, only on the condition that he deals justly with them.
So, Islam came to control having an infinite number of wives, like it was during the Pre-Islamic era.”
RESPONSE:
First of all, Islam wasn’t the only religion that laid restriction to the number of women that a man can marry. Here are some verses from the bible talking about monogamy.
A bishop then must be blameless, the husband of one wife, vigilant, sober, of good behaviour, given to hospitality, apt to teach; (1 Timothy 3:2 )
Let the deacons be the husbands of one wife, ruling their children and their own houses well. (1 Timothy 3:12)
If any be blameless, the husband of one wife, having faithful children not accused of riot or unruly. (Titus 1:6)
"For this reason a man will leave his father and mother and be united to his wife, and the two will become one flesh." (Ephesians 5 :31)
Jesus replied, "Moses permitted you to divorce your wives because your hearts were hard.
