All perfect praise be to Allah, The Lord of the worlds. I testify that there is none worthy of worship except Allah and that Muhammad, sallallahu ‘alayhi wa sallam, is His slave and Messenger.
The earlobes are not part of the face as far as the obligation of washing the face in ablution is concerned; they are a part of the ear, and the ears are not part of the face. The scholars said that the horizontal limit of the face is what is between the two ears.
The author of Daqaa'iq Uli An-Nuha said, "The limit of the face is from the ear to the ear horizontally; i.e. what is between the ears, as they are not part of it (the face)..."
The Maaliki scholar Al-Hattaab wrote, "The horizontal limit of the face is between the two ears. This is clearer than the scholars' statement, 'From ear to ear...'" [Mawaahib Al-Jaleel]
Allah knows best.
