Yahya ibn Yahya and Qutaybah ibn Sa'id narrated to us, both from Ja'far—Yahya said: Ja'far ibn Sulayman informed us—from Abu 'Imran al-Jawni, from Anas ibn Malik, who said: Anas said: "A time limit was set for us regarding trimming the mustache, clipping the nails, plucking the armpit hair, and shaving the pubic hair, that we should not leave them for more than forty nights."
