Musnad Ahmad 1153:575

Yazid ibn Abd Rabbih narrated to us, he said: Baqiyyah narrated to us, he said: Al-Zubaydi narrated to us, from Al-Zuhri, from Urwah ibn al-Zubayr, from Aisha, that the Prophet, peace and blessings of Allah be upon him, said: "Allah, the Almighty and Majestic, will resurrect the people on the Day of Resurrection barefoot, naked, and uncircumcised." She said: Aisha said: "O Messenger of Allah, what about the private parts?" He said: "For every person among them that day will be a matter sufficient to preoccupy him" [Abasa: 37].
