Oral sex

Question:
Is Oral Sex allowed in Islam? What is your supporting information?
Answer:
All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad 
is His slave and Messenger.
Both the husband and the wife can enjoy each other’s body as they wish. Allah Says (what means): {They (your wives) are clothing for you and you are clothing for them.} [Quran 2:187]. Allah also Says (what means): {Your wives are a place of cultivation [i.e. sowing of seed] for you, so come to your place of cultivation however you wish and put forth [righteousness] for yourselves.} [Quran 2:223].
However, one should put the following two conditions into consideration: Firstly, he should avoid what is forbidden in the Islamic law:
A). Making love with the wife in her anus which is a major sin and a sort of homosexuality.
B). Having sexual intercourse with the wife in her vagina but during her menstruation period, because Allah Says (what means): {And they ask you about menstruation. Say, “It is harm, so keep away from wives during menstruation. And do not approach them until they are pure. And when they have purified themselves, then come to them from where Allah has ordained for you. Indeed, Allah loves those who are constantly repentant and loves those who purify themselves.”} [Quran 2:222]
What is meant here is having sex with them. The same ruling applies to the confinement period till the blood stops and the wife performs Ghusl (ritual bath).
Secondly, one should make sure that the manner in which the husband has sex is in conformity with Islamic ethics which are the best morals. As for what you mentioned, i.e. sucking, licking or oral sex, there is no clear evidence from the Quran or the Sunnah concerning them. The scholars differed on this matter. Some believe that it is forbidden, others believe that it is lawful. However, Allah Says (what means): {Your wives are a place of cultivation [i.e. sowing of seed] for you, so come to your place of cultivation however you wish.} [Quran 2:222]. This means in any manner that suits you both but in the place of the cultivation which is the vagina. It does not mean anywhere and anyhow. There is a trace from the Prophet and his companions that backs up this view. One should be cautious not to swallow some dirtiness, as the man might ejaculate in his wife’s mouth. Allah Says (what means): {Truly Allah loves those who turn unto Him in repentance and those who purify themselves.} [Quran 2:222]. This means those who keep themselves above the dirty and the filthy things, which are the cause of forbidding the menstruation period and any part which is not the vagina. This kind of pleasure is far from the natural dispositions that Allah has created us with. Moreover, a tongue that supplicates Allah and recites the Quran should not get in touch with those parts of the body which are a source of some impurity. Indeed what Allah has made lawful for us is enough for any normal person.
Allah knows best.
