Musnad Ahmad 1153:1637

Hammad ibn Usamah narrated to us, he said: Ubaydullah informed us, from Muhammad ibn Yahya ibn Habban, from al-A’raj, from Abu Hurayrah, from Aisha, who said: I missed the Messenger of Allah (peace and blessings of Allah be upon him) one night from the bed, so I sought him, and my hand fell upon the soles of his feet while he was in the mosque, and they were set upright, and he was saying: "O Allah, I seek refuge in Your pleasure from Your anger, and in Your pardon from Your punishment, and I seek refuge in You from You. I cannot enumerate Your praise; You are as You have praised Yourself."
