Musnad Ahmad 1153:251

Yahya narrated to us, from Yahya, from a man, from ‘Amrah, from ‘Aishah, from the Prophet, peace and blessings of Allah be upon him, who said: "Jibril, peace be upon him, continued to advise me regarding the neighbor, until I thought that he would make him an heir." Yahya said: "I think he named Abu Bakr ibn Muhammad to me, but I forgot his name."
