Law of “Anal Sex”
It should not be intercourse with his wife in the anus or in a state of menstruation and childbirth. Even so it includes the major sins according to the word of Allah (meaning):
“They ask you about menstruation. Say “menstruation is dirt.” So shun yourself from a woman when menstruation. And do you approach them before they are holy. If they are holy, then Go to the place which they enjoined. Truly Allah loves those who repent and to love those who purify themselves. Wives you are (like) fields (where farming) for you. So you bagaimanasaja Go to the fields you want. “(Al-Baqarah 222-223)
Allah Subhanahu wa Ta’ala in this paragraph to explain the necessity of distancing themselves from women when in a state of menstruation and forbade to approach them until they are in a state of purity. That shows up
prohibition to intercourse with them when in a state such as menstruation and childbirth also. And if they already purification by bathing, allowed for the husband to come in the place that God commands, which come from the front (qubul), where “farming”
As for the rectum, is not the place where the dirt and planting. Then it should not be intercourse with his wife in the anus even so it includes one of a multitude of sins and the sinners are advised of this holy Shari’ah. Abu Dawud and An Nasa’i has narrated from the Prophet sallallaahu ‘alaihi wa sallam that he said (meaning):
“Terlaknatlah anyone who went to women in the anus”
At Tirmidzy and An Nasa’i meriyawatkan from Ibn Abbas radhiallahu ‘anhuma of the Prophet sallallaahu’ alaihi wa sallam said (meaning),
“God will not look to someone who approach men or women in their anus.” Sanad of this Hadith shohih.
Wife came in the form liwath anus (sodomy) that are forbidden to men and women all. Based on his people the word of Allah, the Exalted Prophet Lut ‘alaihi Assalam (meaning):
“And (remember) when Lut said to his people:” Verily, you are really doing a very heinous act that has not been done by one of the peoples before you “(Al Ankabut 28)
So also the word of the Prophet sallallaahu ‘alaihi wa sallam (meaning):
“God curse anyone who acts with his actions the people of Lut.” He said three times. (Narrated by Imam Ahmad Al sanad shohih).
Then it is obligatory for every Muslim to take care of it and keep away from any that are forbidden by Allah Ta’ala. For every husband should stay away from this munkar. For every wife to abstain from such and not allow the husband to do this great munkar, namely menggaulinya in a state of menstruation or childbirth, or in the rectum.
We ask God for the salvation of the Muslims of every menyelesihi syari’atNya what is sacred. Verily He is the best place to ask. (His Majesty ash Shaykh Abdul Aziz ibn Baaz contracted rahimahullah)
