365. Chapter: On it being forbidden for a man to wear clothes dyed with saffron

1798. Anas said, "The Prophet, may Allah bless him and grant him peace, forbade men to use saffron dye." [Agreed upon]

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]
