口交
Schools of thought (Madh'hab) such as Shafi'i and Hanbali consider fellatio as permissible but only as part of foreplay while all schools regard genital secretion as impure. Oral sex is preferred provided that secretion from the genitalia is not consumed and no injury or infliction made. The consumption of semen on the other hand is believed to be permissible by some scholars. However, the stronger view is that it is not allowed. The couple has to rinse their mouth afterwards to maintain cleanliness. According to a fatwa written by Shaykh Muhammad bin Saalih al-`Uthaymeen, the couple may then sleep in the bed in which semen was secreted since semen is seen as a pure substance under Islamic law; however, this is contingent upon the man's cleanliness. If the husband has not washed himself after urination and before oral sex then the semen will become unclean.
