In ritual ablution (wudu'), does washing the forearms begin from the fingertips, and is it correct to raise the palm of the hand upwards?

The entire hand must be washed from the fingertips to the elbows, and the elbow is included in the washing according to the majority of scholars. It is recommended to start washing from the fingertips in all cases, whether one washes by himself or someone else pours water for him.
