Musnad Ahmad 1153:884

'Affan narrated to us, Wuhayb narrated to us, he said: 'Abdullah ibn 'Uthman ibn Khuthaym narrated to us, from Ibn Abi Mulaykah, from 'Aishah, she said: I heard the Messenger of Allah, peace and blessings of Allah be upon him, saying: "I am at the Basin (al-Hawd) waiting for those of you who will come to it to meet me. Men will certainly be cut off from me, so I will say: 'O my Lord, my nation, my nation!' It will be said to me: 'You do not know what they did after you; they continued to turn back on their heels.'"
