Musnad Ahmad 1153:78

Sufyan narrated to us, from al-Zuhri, from Urwah, from Aisha, that the Prophet (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: "Its markings distracted me. Take it to Abu Jahm, and bring me an *anbijaniyyah* (a plain, thick garment)."
