A complete guide to everything that invalidates your Wudu (ablution), with evidence from the Quran, Sunnah and the four major schools of thought.
Wudu (ablution) is a prerequisite for Salah (prayer) and other acts of worship. Understanding what breaks your Wudu helps you maintain ritual purity. If you need to learn how to perform Wudu, see our step-by-step Wudu guide.
The following invalidate Wudu according to all four madhabs (Hanafi, Maliki, Shafi'i, Hanbali):
Urine, stool, gas (flatulence), and any discharge from the private parts — including madhiy (pre-seminal fluid) and wadiy — all break Wudu. The Prophet ﷺ said: "He should not leave (the prayer) unless he hears a sound or smells something." (Bukhari & Muslim)
Deep sleep where you lose awareness of your surroundings breaks Wudu. Light dozing while sitting upright is generally excused (Hanafi, Shafi'i positions), but if you lean, lie down or fall to one side, your Wudu is invalidated.
Fainting, anaesthesia, intoxication or any state that causes you to lose awareness of your surroundings breaks Wudu, as you cannot know if something exited the body during that time.
Touching your own private parts with the palm or inner fingers (without a barrier) breaks Wudu according to the majority of scholars (Shafi'i, Maliki, Hanbali). The Hanafi position is that it does not break Wudu unless there is discharge, but the majority view is stronger in evidence.
The following have different rulings depending on the madhab you follow:
Hanafi: Blood that flows from the wound breaks Wudu.
Shafi'i, Maliki, Hanbali: Bleeding does NOT break Wudu (only blood from the front/back passage does).
Hanafi: Vomiting a mouthful breaks Wudu.
Shafi'i, Maliki, Hanbali: Vomiting does NOT break Wudu, though renewing Wudu is recommended.
Shafi'i: Touching skin-to-skin with a non-mahram of the opposite gender breaks Wudu.
Hanafi: Does NOT break Wudu unless accompanied by desire.
Maliki: Breaks Wudu only if accompanied by desire or pleasure.
Hanbali: Breaks Wudu if touched with desire.
Hanbali: Breaks Wudu based on an authentic hadith where the Prophet ﷺ instructed to make Wudu after eating camel meat (Muslim).
Hanafi, Shafi'i, Maliki: Does NOT break Wudu, though renewing is recommended as a precaution.
Hanafi: Loud laughter (that others can hear) during Salah breaks both the prayer AND the Wudu.
Shafi'i, Maliki, Hanbali: Breaks the prayer but NOT the Wudu.
