Sayyidah Aishah (may Allah be pleased with her) said: When the Messenger of Allah (peace and blessings be upon him) took the ritual bath for janabah, he would call for something like a large bowl, then take a handful of water and begin with the right side of his head, then the left side, then take water with both palms and pour it over his head.
(b) 'Al-hilab' means the vessel in which milk is drawn; it was called hilab.
