Musnad Abu Ya'la al-Mawsili 150:20

Ishaq narrated to us, Sufyan narrated to us, from al-Zuhri, from al-Qasim ibn Muhammad, from Aisha, who said: The Prophet, may Allah bless him and grant him peace, entered upon me while I had screened myself with a curtain (qiram) that had images on it. When he saw it, his face changed color, and he tore it down. He said: "Indeed, the people who will receive the severest punishment on the Day of Resurrection are those who imitate the creation of Allah."
