'Abdullah bin 'Amr bin Al-'As (May Allah be pleased with them) said

The Prophet ﷺ me dressed in two saffron-coloured garments and asked, "Has your mother commanded you to wear these?" I asked him, "Shall I wash them out?" He replied, "You had better set them to fire."

Another narration is: "These are garments of the disbelievers. So do not wear them."
