Riyad as-Salihin (The Meadows of the Righteous)
by Imam Nawawi
1799. 'Abdullah ibn 'Amr ibn al-'As said, "The Prophet, may Allah bless him and grant him peace, saw me wearing two garments dyed with saffron and he said, 'Did your mother order you to do this?' I said, 'Shall I wash them?' He said, 'Rather burn them.'"
In one variant, "This is clothing that the unbelievers wear, so do not wear it." [Muslim]
