Everything is for a reason in Islam

Wudu... the fard of wudu are 4.
(1) washing the face from the forehead to the lower portion of the chin and from one ear to the other;
(2) washing of both the arms up to the elbows;
(3) doing masah, covering at least quarter of the head;
(4) washing of both the feet up to ankles.

Wudu can only be performed with water whose texture, taste or smell hasn't changed.

Now, think back on how we perform wudu and what do we start with. :)

It makes perfect sense!!!
