The Invalidators of Wudu'

The invalidators of wudu' are matters which break wudu'. When one’s wudu’ is invalidated, one must make wudu' again to pray. The invalidators are:

        Materials exiting from the eliminatory outlets, such as urine, feces, gas, or stomach worms.

        Touching the anus, vagina, or penis with one's bare palm.

        Touching the skin of the marriageable woman without a barrier.

        Losing one's mind by craziness, fainting, or intoxication.

        Sleeping without having one's buttocks firmly seated. If one slept without a gap between one's buttocks and the floor, then one’s wudu' would not be invalid.
