Let us look at the position of women in Islam:
1). A woman's testimony is worth half that of a man.
2). A woman inherits half of what a man inherits.
3). Women are places of cultivation for their husbands and can be beaten by them for disobedience.
Let's examine the Quran and the Hadiths:
4:11 - Allah instructs you concerning your children: for the male, what is equal to the share of two females.
2:282 - And bring to witness two witnesses from among your men. And if there are not two men [available], then a man and two women from those whom you accept as witnesses - so that if one of the women errs, then the other can remind her.
2:223 - Your wives are a place of sowing of seed for you, so come to your place of cultivation however you wish and put forth [righteousness] for yourselves.
4:34 - Men are in charge of women by [right of] what Allah has given one over the other and what they spend [for maintenance] from their wealth. So righteous women are devoutly obedient, guarding in [the husband's] absence what Allah would have them guard. But those [wives] from whom you fear arrogance - [first] advise them; [then if they persist], forsake them in bed; and [finally], strike them. But if they obey you [once more], seek no means against them.
Sahih al-Bukhari 2658 - Narrated Abu Sa`id Al-Khudri: The Prophet said, "Isn't the witness of a woman equal to half of that of a man?" The women said, "Yes." He said, "This is because of the deficiency of a woman's mind."
Sunan Abu-Dawud 2146 - Iyas ibn Abdullah ibn Abu Dhubab reported the Messenger of Allah as saying: Do not beat Allah's handmaidens, but when Umar came to the Messenger of Allah and said: Women have become emboldened towards their husbands, he (the Prophet) gave permission to beat them. Then many women came round the family of the Messenger of Allah complaining against their husbands. So the Messenger of Allah said: Many women have gone round Muhammad's family complaining against their husbands. They are not the best among you.
And if all of these weren't bad enough, here's the final straw. Physical abuse of women happens right in front of Muhammad by his closest companions and guess what he did? He laughed and watched.
Sahih Muslim 1478 - Jabir b. 'Abdullah (Allah be pleased with them) reported: Abu Bakr (Allah be pleased with him) came and sought permission to see Allah's Messenger. He found people sitting at his door and none amongst them had been granted permission, but it was granted to Abu Bakr and he went in. Then came 'Umar and he sought permission and it was granted to him, and he found Allah's Apostle sitting sad and silent with his wives around him. He (Hadrat 'Umar) said: I would say something which would make the Prophet laugh, so he said: Messenger of Allah, I wish you had seen (the treatment meted out to) the daughter of Khadija when you asked me some money, and I got up and slapped her on her neck. Allah's Messenger (mav peace be upon him) laughed and said: They are around me as you see, asking for extra money. Abu Bakr (Allah be pleased with him) then got up went to 'A'isha (Allah be pleased with her) and slapped her on the neck, and 'Umar stood up before Hafsa and slapped her saying: You ask Allah's Messenger which he does not possess. They said: By Allah, we do not ask Allah's Messenger for anything he does not possess. Then he withdrew from them for a month or for twenty-nine days. Then this verse was revealed to him:" Prophet: Say to thy wives... for a mighty reward" (xxxiii. 28).
Perhaps nothing could sum up Islam's attitude towards women better than Muhammad's "Farewell Sermon", found in the Siras and Hadiths. Women are compared to "domestic animals" men possess. Some other translators translate it is "prisoners with you".
Al-Tabari, Vol. 9, pp. 112-113 - "O people, you have a right over your wives and they have a right over you. You have [the right] that they should not cause anyone of whom you dislike to tread on your beds; and that they should not commit any open indecency (fahishah). If they do, then God permits you to shut them in separate rooms and to beat them, but not severely. If they abstain from [evil], they have the right to their food and clothing in accordance with custom (bi’l-ma‘ruf). Treat women well, for they are [like] domestic animals ('awånin) with you and do not possess anything for themselves. You have taken them only as a trust from God, and you have made the enjoyment of their persons lawful by the word of God, so understand and listen to my words, O people.
NOTE: The above teachings are also found in Sirat Rasulallah by Ibn Ishaq as well as the hadiths - Jami At-Tirmidhi 104 and Sunan Ibn Majah 1851.
