It is narrated from Sayyiduna Abu Abdullah al-Ansari al-Khatmi (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Five things are among the practices (sunan) of the Prophets: modesty, forbearance, cupping, using the tooth-stick (siwak) and applying perfume."
