Musnad Abu Ya'la al-Mawsili 129:149

On the authority of Anas bin Malik, may Allah be pleased with him, he 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 or brocade softer than the palm of the Messenger of Allah, may Allah bless him and grant him peace.
