Jami` at-Tirmidhi Book 43, Hadith 26
that the Messenger of Allah (ﷺ) said: "Five are from the Fitrah: Cutting the pubic hair, circumcision, paring the mustache, plucking the under arm hair and trimming the fingernails."
that Mu'awiyah came out and 'Abdullah bin Az-Zubair and Ibn Safwan stood for him when they saw him, so he said: "Sit, I heard the Messenger of Allah (ﷺ) saying: 'Whoever wishes that he be received by men standing then, let him take his seat in the Fire.'"
that the Prophet (ﷺ) said: "Ten are from the Fitrah: Paring the mustache, leaving the beard to grow, Siwak, cleaning the nose with water, paring the fingernails, washing the knuckles, plucking the underarm hair, shaving the pubic hairs, and Intiqas with water."
