Musnad Ahmad 28:453

Yazid ibn Harun narrated to us, Hisham informed us, and Abd al-Samad said: Hisham narrated to us, from Yahya, from Muhammad ibn Ibrahim ibn al-Harith, that Khalid ibn Ma'dan narrated to him, that Jubayr ibn Nufayr narrated to him, that Abdullah ibn Amr informed him—Abd al-Samad said: Ibn al-As narrated to him—that the Prophet, peace and blessings of Allah be upon him, saw two saffron-dyed garments on him. He said: "Indeed, these are the garments of the disbelievers, so do not wear them."
