Musnad Ahmad 32:108

Ibn Abi ‘Adi narrated to us, from Humayd, who said: Anas ibn Malik said: "I have never touched anything at all—neither silk nor brocade—softer than the palm of the Messenger of Allah, may Allah bless him and grant him peace. And I have never smelled a scent more pleasant than the scent of the Messenger of Allah, may Allah bless him and grant him peace."
