Musnad Ahmad 1153:1093

Yazid narrated to us, he said: Hammad informed us, and 'Affan said: Hammad ibn Salamah narrated to us, from Ayyub—'Affan said: And Ayyub narrated to us—from Abu Qilabah, from 'Abdullah ibn Yazid, from 'Aishah, she said: The Messenger of Allah, peace and blessings of Allah be upon him, used to divide [his time] among his wives and act justly. 'Affan said: And he would say, "This is my division." Then he would say, "O Allah, this is my action regarding what I possess, so do not blame me for what You possess and I do not possess."
