Musnad Ahmad 32:719

'Abd al-Razzaq narrated to us, Ma'mar narrated to us, from Qatadah and Thabit, from Anas, that he heard the Messenger of Allah (may Allah bless him and grant him peace) — or he said: "Indeed, the Messenger of Allah (may Allah bless him and grant him peace) said: 'Indeed, some people will emerge from the Fire, having been scorched by the Fire as a punishment for sins they committed. Allah will bring them out by the grace of His mercy, and they will enter Paradise.'"
