2. Filth (najâsat - substances which Islam prescribes as filthy) has been removed from the body, clothes and place of prayer.

2. Washing the hands and lower arms to above the elbow.
3. Washing the feet to above the ankles.

   Note: One must remove all obstacles for the water to reach (e.g. tight rings, mucus, make-up.)

Causes of minor ritual impurity (things that invalidate ones ablution)

1. EVERYTHING excreted from the front and rear organs, even air or a worm.
2. Vomiting the amount of a mouthful unless it is phlegm.
3. Blood or pus flowing out of a wound to a place required to wash in the full body wash (ghusl) (the skin, hair, mouth, inside the soft part of the nose, not inside the eyes.) Exempted are: bleeding from a wound in the mouth itself that does not make the spit red or thick black blood coming down from the head into the mouth or nose.
4. Sleeping, unless one is sitting firmly on one's seat, thus preventing the exit of air.
5. Fainting, going crazy, or having an epileptic fit (without exceptions.)
6. Laughter loud enough for others to hear it during a prayer that has bowing and prostration, unless one is a child.
7. Intense sexual contact breaks the ablution', that is, when a man and woman physically rub their private parts on each other.
