Musnad Ahmad 1153:1716

Waki’ narrated to us, from Hisham, from his father, from Aisha, that the Prophet, peace and blessings of Allah be upon him, had a *khamisa* (a square garment) with markings. He would be distracted by its markings during the prayer. So, he gave it to Abu al-Jahm and took an *anbijani* (a coarse, plain garment) cloak of his.
