Musnad Ahmad 1153:795

Husayn narrated to us, he said: Abu Uways narrated to us, he said: Hisham ibn Urwah narrated to us, from his father, from Aisha, that she bought a patterned cloth (namat) in which there were images, and she wanted to make it into a curtain (hajlah). The Prophet, peace and blessings of Allah be upon him, entered upon her, and she showed it to him, and informed him that she wanted to make it into a curtain. He said to her: "Cut it into two pillows." She said: So I did, and I would lean upon them, and the Prophet, peace and blessings of Allah be upon him, would lean upon them.
