Musnad Ahmad 509:5

Muhammad ibn Ja‘far narrated to us, Shu‘bah narrated to us, from ‘Ata’ ibn al-Sa’ib, from Abu ‘Amr ibn Hafs, or Abu Hafs ibn ‘Amr, from Ya‘la ibn Murrah, who said: The Messenger of Allah (may Allah bless him and grant him peace) saw *khuluq* (a yellow perfume) on me, so he said: "Do you have a wife?" I said: "No." He said: "Then go and wash it off, and do not return to it."
