Sayyiduna Abdullah bin Yazid al-Khatmi narrates this from his father: The Prophet (peace and blessings be upon him) said: "Five things are among the sunnahs of the Messengers: modesty, forbearance, cupping, using the siwak, and applying perfume."
Al-Tabarani recorded it. Its chain contains a narrator, Umar bin Muhammad al-Aslami. Al-Dhahabi said: He is majhul (unknown). Al-Hakim (may Allah have mercy on him) recorded a hadith through him in al-Mustadrak, and more than one person has narrated from him.
