Musnad Ahmad 1153:985

'Affan narrated to us, Hammam narrated to us, he said: Qatadah narrated to us, from Mutarrif, from 'Aishah: "That she made for the Prophet, may Allah bless him and grant him peace, a black cloak of wool. She mentioned its blackness and his whiteness, and he wore it. When he sweated and sensed the smell of the wool, he cast it off, and he used to love a pleasant scent."
