According to Al-Qayrawani’sThe Risala on the Maliki Madhhab, wudu’ is obligatory in the case of what comes from either of the two openings, such as urine, excrement or gas. In the case of madhi (pre-seminal fluid) from the penis, it is obligatory to wash the entire penis from it. Madhi is a clear liquid discharged on the occasion of a pleasurable erection during foreplay or lustful thinking. Wadi is a thick clear liquid which comes out after urinating; the rule for this is the same as that for urine. Mani (semen) is a gushing liquid which comes out [of a man] on the occasion of the greatest pleasure in intercourse, and smells like a date palm blossom; in the case of a woman it is a fine and yellow liquid. Purification from mani is obligatory; moreover the whole body must be purified [by hhusl (ritual bath), just as the case after menstruation.”
Al-Qayrawani states elsewhere: “A fasting person should not approach women by way of intercourse, embracing or kissing for the sake of sexual pleasure during the day in Ramadan, but at night these things are not forbidden to him. There is no harm when morning comes for someone to be in a state of major sexual defilement because of intercourse, but if someone seeks pleasure during the day from embracing or kissing, and releases madhi because of it, he must make up for the vitiated fast. Moreover, if he does these things deliberately and ejaculates mani as a result, he must make Kaffara (atonement).”
Thus, madhi breaks fasting according to the Maliki School.
However, the view believed to be the most preferred amongst scholars is that madhi does not break fasting.
Sheikh Ibn `Uthaymeen (may Allah bless his soul) states in one of his fatwas: Madhi does not break one’s fasting, according to the preferred opinion of jurists. That is because one can hardly restrain it.
It is also stated in the Kuwaiti Encyclopedia of Fiqh: If someone releases madhi due to a lustful look, the preferred opinion is that of Imam Ahmad that it does not invalidate the fast since there is no proof for that. The saying that it takes the ruling of mani by virtue of qiyas (analogical deduction) is unsubstantiated because there is a difference between the ruling of madhi and mani.
Sheikh Hamed Al-`Ali, instructor of Islamic Heritage at the Faculty of Education, Kuwait and Imam of Dahiat As-Sabahiyya Mosque, adds:
“The view believed to be the most correct amongst scholars is that madhi does not break the fast, and there is no daleel that it does break the fast, whether in Ramadan or in fasting kaffara. As for the wadi, it has nothing to do with sexual excitement as it comes after urine and it has the same ruling like urine; therefore it does not invalidate the fast.”
In his book Fiqh-us-Sunnah, the late Sheikh Sayyed Sabiq (may Allah bless his soul) states:
“Ejaculation of mani voids the fast even if it was just due to kissing, hugging, or masturbation, and the day must be made up. If the ejaculation relates to looking at or thinking about something, then it is like having a wet dream during the day and it, therefore, does not void the fast nor is there any requirement on the person. Similarly, ejaculation of madhi does not harm the fast in any way.”
