Musnad Abu Ya'la al-Mawsili 115:299

Ubayd Allah narrated to us, Harami ibn 'Amarah narrated to us, Shu'bah narrated to us, from Qatadah, from Anas, that the Messenger of Allah (peace and blessings of Allah be upon him) said: "It will be cast into the Fire, and it will say, 'Are there any more?' until the Blessed and Exalted One places His foot into it—or he said: His step—then it will say, 'Enough, enough.'"
