The Sunni schools of jurisprudence (known as "madhaahib" – the "Hanafi", "Shafi'i", "Maliki", "Hanbali, and Zahiri" schools of "Fiqh") have differing stances on the issue. Some see it forbidden in certain cases (i.e. if it leads a man/woman to ignore their spouse sexually) but recommended it when they see it as a lesser evil to illicit sex. It is generally prohibited according to the "Hanafi" and "Hanbali" "madhaahib", unless one fears adultery or fornication, or is under the desire pressure, in which case, it is permissible to seek a relief through masturbation. It is prohibited all the time according to the "Maliki" and "Shafi"`i "madhaahib". Zahiri Imam Ibn Hazm regards masturbation as permissible. Scholars have also stated that masturbation would not be necessary if one realizes the flexible approach Islam takes to marriage. For example, according to Sheikh Shomeh Yerkity, 'against the clear teachings of Islam, marriage has been rendered another difficult process today due to warped customs and conventions and undue expectations. When we approach marriage from the point of view of pristine Islam, we shall find less and fewer people being forced to exercise the above type of exceptional rulings'. Yet if one's desire is so overwhelming one might perform masturbation but in that case it will be like eating the flesh of a pig to survive from major hunger or starvation when no other food is available.
