Musannaf Ibn Abi Shayba 27:80

Yazid ibn Harun narrated to us, from Humayd, from Anas, who said: I have never smelled a scent, neither musk nor ambergris, more pleasant than the scent of the Messenger of Allah, may Allah bless him and grant him peace. And I have never touched silk nor brocade softer than the palm of the Messenger of Allah, may Allah bless him and grant him peace.
