What are the Obligations of Al-Wudu?

[Islamkingdom_En]

1- Intention: Intentions are made in the heart and are not to be pronounced out loud, i.e. audibly. If al-wudu’ is done for a purpose other than purification for worship, such as cooling off or cleaning the body, then it is not valid to perform worship with it.
2- Washing the face. Al-Istinshaq is part of washing the face.
3- Washing of the hands and forearms, including the elbows.
4- Washing of the feet and ankles.
5- Rubbing the head entirely (this includes the ears).
6- Washing these parts one after the other in the order mentioned above.

[Ümit]

According to the Hanafis...we have the well known 32 obligations in İslam. We ought to know these 32 obligations by heart and every hanafi imaam will active teach them to his pupils.

4 of these 32 obligations are about wudu:
1 to wash the face. The face is the area between the 2 earlobes, chin and hairline. (Ears are not included)
2 wash arms including elbows
3 do mesh on the quarter part of the head
4 wash feet including ankles

The ears are sunnah so they are not included in the obligations
