Musnad Ahmad 28:37

Yahya narrated to us, from Hisham al-Dastawa'i, Yahya narrated to us, from Muhammad ibn Ibrahim, from Khalid ibn Ma'dan, from Jubayr ibn Nufayr, from Abdullah ibn Amr, that the Messenger of Allah (may Allah bless him and grant him peace) saw him wearing two saffron-dyed garments. He said: "These are the garments of the disbelievers, so do not wear them."
