Musnad Ahmad 1153:1865

'Abd al-Razzaq narrated to us, Isra'il narrated to us, from Simak, from 'Ikrimah, from 'A'ishah, she said: The Messenger of Allah (peace and blessings of Allah be upon him) used to raise his hands in supplication, until I would become weary for him because of how long he would raise them, supplicating: "O Allah, I am only a human being, so do not punish me for the reviling of a man whom I have reviled or harmed."
