Sex in Islam, - Islamic Ruling on Anal Sex

In the Name of Allah, Most Gracious, Most Merciful.
All praise and thanks are due to Allah, and peace and blessings be
upon His Messenger.
Almighty Allah says in the Qur'an:"Your wives are a tilth for you, so
go to your tilth, when or how you will, and send (good deeds, or ask
Allah to bestow upon you pious offspring) for your ownselves
beforehand. And fear Allah, and know that you are to meet Him (in the
Hereafter), and give good tidings to the believers."(Al-Baqarah: 223)
In the foregoing verse the wordHarth(tilth) indicates that only
vaginal sex is permissible in Islam, because it is from this place
children are produced. The semen lodged in the womb from which
offsprings come is likened to the seeds that are planted in the
ground, bringing vegetation. Both of them are substances from which
something else is produced.
All Muslim jurists agree that anal sex is Haram, based on the Hadith
of the Prophet, peace and blessings be upon him:"Do not have anal sex
with women."(Reported by Ahmad, At-Tirmidhi, An-Nasaa'i, and Ibn
Majah.)
Khuzaymah Ibn Thaabit, may Allah be pleased with him, also reports
that the Messenger of Allah, peace and blessings be upon him,
said:"Allah is not too shy to tell you the truth: Do not have sex with
your wives in the anus."(Reported by Ahmad, 5/213.)
Ibn `Abbaas, may Allah be pleased with him, narrates: "The Messenger
of Allah, peace and blessings be upon him, said:"Allah will not look
at a man who has anal sex with his wife."(Reported by Ibn Abi Shaybah,
3/529, and At-Tirmidhi classified it as an authentic Hadith, 1165.)
Further, it is reported that the Prophet, peace and blessing be upon
him, referred to such an act as"minor sodomy."(Reported by Ahmad and
An-Nasaa'i.)
However, it is allowed to caress the wife and stimulate her around the
anus, without having sex in this area. It is reported that `Umar Ibn
Al-Khattaab, may Allah be pleased with him, came one day to the
Prophet and said, "O Messenger of Allah, I am ruined!""What has ruined
you?"asked the Prophet. He replied, "Last night I turned my wife
over," meaning that he had had vaginal intercourse with her from the
back. The Prophet, peace and blessings be upon him, did not say
anything to him until the verse cited above was revealed. Then he told
him,"From the front or the back, but avoid the anus and intercourse
during menstruation."(Reported by Ahmad and At-Tirmidhi.)
If one does have anal sex with his wife, he has committed a grave sin,
which requires repentance. He should regret and feel contrite for
committing such a sin. Allah Almighty destroyed a whole nation who
were accustomed to this evil habit.
But the wife is not considered divorcedas many people think, because
there is no evidence to support this view. However, scholars maintain
that if a man habitually does this or insists on having anal sex with
his wife, she has the right to ask for a divorce, because he is
considered an evildoer who is causing harm by his action, and also
because the purpose of marriage cannot be achieved through this
action.
The wife has to resist this evil action and refuse to respond to her
husband's desire to have anal sex. She should remind him of Allah as
well as the punishment of those who transgresses the Bounds set by
Allah.
Allah Almighty knows best.
