Miqdam bin Ma'dikarib (may Allah be pleased with him) said: I saw the Messenger of Allah (peace and blessings be upon him) performing ablution. When he (peace and blessings be upon him) reached the wiping of the head, he placed his palms on the front part of his head, then took them to the nape, then brought them back to the place where he had started.
(b) Hariz (may Allah have mercy on him) said: Then he (peace and blessings be upon him) raised (his hands).
