Musnad Ahmad 1153:289

Ibn Numayr narrated to us, he said: Hisham narrated to us, from his father, from Aisha, who said: "I used to play with dolls, and my female companions would come and play with me. When they saw the Messenger of Allah (peace and blessings of Allah be upon him), they would hide themselves from him. The Messenger of Allah (peace and blessings of Allah be upon him) would send them in to me, so they would play with me."
