Humayd bin Abd al-Rahman al-Himyari (may Allah have mercy on him) said: I met a Companion, just as Sayyiduna Abu Hurayrah (may Allah be pleased with him) is a Companion. He said that the Prophet (peace and blessings be upon him) forbade us from "combing the hair every day and urinating in the bathing place."
