Musnad Ahmad 32:2047

'Affan narrated to us, Wuhayb narrated to us, 'Abd al-'Aziz ibn Suhayb narrated to us, from Anas ibn Malik, from the Prophet, peace and blessings of Allah be upon him, who said: "Men will certainly come to me at the Basin (al-Hawd). Until, when I see them and they are raised up to me, they will be snatched away from before me. I will surely say: 'O my Lord, my companions, my companions!' It will be said: 'Indeed, you do not know what they innovated after you.'"
