Musnad Ahmad 26:130

'Ammar ibn Muhammad, the nephew of Sufyan al-Thawri, narrated to us, from Ibrahim, from Abu al-Ahwas, from 'Abdullah, who said: The Messenger of Allah (peace and blessings of Allah be upon him) said: "Indeed, Allah, the Almighty and Majestic, will send forth a caller on the Day of Resurrection who will call out: 'O Adam, indeed Allah commands you to send forth a contingent from your offspring to the Fire.' Adam will say: 'O Lord, and how many?' It will be said to him: 'From every hundred, ninety-nine.'" A man from the people said: "Who is this survivor among us after this, O Messenger of Allah?" He said: "Do you know what you are among the people? You are among the people only like a mole on the chest of a camel."
