Musnad Ahmad 1153:1617

'Abd al-Razzaq narrated to us, Ma'mar narrated to us, from al-Zuhri, from 'Urwah, from 'Aishah, who said: "The Messenger of Allah (peace and blessings of Allah be upon him) prayed in a *khamisah* (a square garment) that had markings. When he finished his prayer, he said: 'Take this *khamisah* to Abu Jahm, and bring me an *anbijaniyyah* (a plain woolen garment), for it distracted me just now from my prayer.'"
