Musnad Ahmad 32:1458

Yunus narrated to us, Shaiban narrated to us, from Qatadah, and he mentioned something of the interpretation. He said: Regarding His saying: {The Day We will say to Hell, "Have you been filled?"} [Qaf: 30], he said: Anas ibn Malik narrated to us that the Prophet of Allah, peace and blessings of Allah be upon him, said: "Hell will continue to say, 'Is there any more?' until the Lord of Might places His foot into it. Then it will say, 'Enough, enough, by Your Might,' and some of it will be drawn together to the rest."
