Some years ago in Nigeria an un-married Moslem woman was raped. She took the man to court but she could not produce three witnesses to convict him.
He was released.
Months later she began to show. Her pregnancy and her un-married status meant she was then arrested for adultery. The evidence was there in her belly.
She faced stoning for this offence.
It was only due to a major international outcry that she was saved.
That's Islam for you.
O sheikh montalban
Can you tell us the verses in the Qur'an that recommends such a severe punishment?
Well every other time I've provided evidence, you've ignored it.
I note here your question is itself loaded; by calling for evidence only from the Koran
"Islamic Sharia Law is based on the Quran, the hadith, and the biography of the prophet Muhammad. Shia and Sunni hadith collections differ because scholars from the two traditions differ as to the reliability of the narrators and transmitters and the Imamah. Shi'a sayings related to stoning can be found in Kitab al-Kafi, and Sunni sayings related to stoning can be found in the Sahih Bukhari and Sahih Muslim.
Based on these hadiths, in some Muslim countries, such as Afghanistan, Iran, Nigeria and Saudi Arabia, married adulterers will get capital punishment, while not-married adulterers will be flogged 100 times.
The Qur'an forbids all sexual intercourse outside the marital bond as sinful, but makes no distinction between them. The punishment is flogging 100 times for those found guilty. Stoning (rajm) as a punishment for adultery is not mentioned in the Quran (though it is mentioned in Hadith), so a few modernist Muslim scholars, like Quran alone Muslim Scholars, take the view that stoning to death is not an Islamic law.
According to the Hanbali jurist Ibn Qudamah, "Muslim jurists are unanimous on the fact that stoning to death is a specified punishment for the married adulterer and adulteress. The punishment is recorded in number of traditions and the practice of Muhammad stands as an authentic source supporting it. This is the view held by all Companions, Successors and other Muslim scholars with the exception of Kharijites."
Because the word used in the Quran, 'zina', is exactly parallel to the Hebrew 'zanah', which strictly refers to fornication and not adultery (which is 'na'aph'), the Quran may not even be speaking of adultery at all. In that case, the point could be made that the command of the Torah on the punishment of adultery, namely, stoning to death, still stands. However, this is not the usual reason that Muslims support stoning for adultery, as most do not hold the Bible to be reliable, and instead derive from the hadiths.
In hadith (sayings)
Sahih Muslim, Book 17, Chapter 6: Stoning to Death of Jews and Other Dhimmis In Cases of Adultery, Number 4216: Jabir b.'Abdullah reported that Allah's Apostle stoned (to death) a person from Banu Aslam, and a Jew and his wife.
Sahih Bukhari 6.79, Narrated by Abdullah ibn Umar
The Jews brought to the Prophet a man and a woman from among them who had committed illegal sexual intercourse. The Prophet said to them, "How do you usually punish the one amongst you who has committed illegal sexual intercourse?" They replied, "We blacken their faces with coal and beat them." He said, "Don't you find the order of Ar-Rajm (i.e. stoning to death) in the Torah?" They replied, "We do not find anything in it." 'Abdullah bin Salam (after hearing this conversation) said to them, "You have told a lie! Bring here the Torah and recite it if you are truthful." (So the Jews brought the Torah). And the religious teacher who was teaching it to them, put his hand over the Verse of Ar-Rajm and started reading what was written above and below the place hidden with his hand, but he did not read the Verse of Ar-Rajm. 'Abdullah bin Salam removed his (i.e. the teacher's) hand from the Verse of Ar-Rajm and said, "What is this?" So when the Jews saw that Verse, they said, "This is the Verse of Ar-Rajm." So the Prophet ordered the two adulterers to be stoned to death, and they were stoned to death near the place where biers used to be placed near the Mosque. I saw her companion (i.e. the adulterer) bowing over her so as to protect her from the stones.
Sahih Bukhari, Volume 3, Book 50: Conditions, Number 885: Narrated Abu Huraira and Zaid bin Khalid Al-Juhani: A bedouin came to Allah's Apostle and said, "O Allah's apostle! I ask you by Allah to judge My case according to Allah's Laws." His opponent, who was more learned than he, said, "Yes, judge between us according to Allah's Laws, and allow me to speak." Allah's Apostle said, "Speak." He (i .e. the bedouin or the other man) said, "My son was working as a laborer for this (man) and he committed illegal sexual intercourse with his wife. The people told me that it was obligatory that my son should be stoned to death, so in lieu of that I ransomed my son by paying one hundred sheep and a slave girl. Then I asked the religious scholars about it, and they informed me that my son must be lashed one hundred lashes, and be exiled for one year, and the wife of this (man) must be stoned to death." Allah's Apostle said, "By Him in Whose Hands my soul is, I will judge between you according to Allah's Laws. The slave-girl and the sheep are to be returned to you, your son is to receive a hundred lashes and be exiled for one year. You, Unais, go to the wife of this (man) and if she confesses her guilt, stone her to death." Unais went to that woman next morning and she confessed. Allah's Apostle ordered that she be stoned to death."http://en.wikipedia.org/wiki/Stoning#In_Islam
