Hadith 157
Ishaq bin Isa reports that I asked Imam Malik, may Allah have mercy on him, about a person who only wiped his forehead during ablution; would that be sufficient for him? He replied that Amr bin Yahya bin Amarah narrated to me from his father, and he from Sayyiduna Abdullah bin Zaid Mazni, may Allah be pleased with him, that he stated: The Messenger of Allah, peace and blessings be upon him, wiped his head in ablution from his forehead to the nape of his neck, then returned his hands to his forehead and wiped the entire head.
