Sex in Islam
Answer to a Question About Oral Sex
By Dr. Muzammil H. Siddiqui, President: Islamic Society of North America (ISNA)
Is oral sex with your legal wife, of course, allowed in the Islam.
Wa Alaikum Salaam,
There is no clear prohibition about oral sex in the Qur'an or the sunnah of the Prophet (SAAWS). However, according to many jurists, the fluids that the male of female organs emit during the time of sexual excitement, such as many (sperm) or madhi; etc., are all considered negis and they should not touch the mouth of the man or the woman. It is for this reason that many scholars do not recommend this practice and consider it makrooh.
