Question 2) - List those organs which must be washed or wiped during wudu?

A: They are:

1. The face from the hairline to bottom oboe cam the right ear-lobe to the left ear-lobe.
2. The hands from the fingertips to the elbows.
3. The feet from the tips of the toes till the ankles - these three organs must be washed completely or the wudu is invalid. Even if the space of a hair is not washed he will not be mutawadi until water reaches that place.
4. The part which must be wiped is the head. It is Sunnah to wipe the entire head, but if a quarter of the beau' is wiped the Fard amount is sufficed.
