First get some water in your right hand and then pour it onto your forehead, where the hair grows. You have to wash the whole length of your face, beginning from your forehead (where the hair grows) and ending at the bottom of the chin.
You have to wash the whole width of your face. You do this by stretching your hand out (from your thumb to your middle finger). To make sure that the whole width has been washed, you should pass your wet hand on either side of your face.
Washing of the face once is Wajib. It is Mustahab to wash your face twice – washing 3 or more times Is Haraam
THE FACE AND HANDS SHOULD BE WASHED FROM ABOVE DOWNWARDS, AND IF YOU WASH IT THE OPPOSITE WAY, WUDHU WILL BE BATIL- Masail No. 249
Then you wash your arms from the elbow to thefingertips. First the right arm is washed with the left hand, then the left arm is washed with the right hand.
To ensure that each elbow is washed thoroughly, you must pour water and begin wiping slightly above the elbow.
Washing of the arms once is Wajib. It is Mustahab to wash your arms twice, washing 3 or more times is Haraam
After that is done, you do Masah of the head and this is done by wiping the wet three fingers of the right hand from the middle of the head up to the edge of the hair, without touching the forehead.
The water of the face and head should not join.

Finally you do Masah of the feet and this is done by wiping the wet fingers of the right hand over the upper part of the right foot from the tip of the toes to the ankle.
Then the same is done with the left hand for the left foot.
