Musnad Abu Ya'la al-Mawsili 115:196

Muhammad ibn Mahdi narrated to us, Abd al-Razzaq narrated to us, Ma'mar informed 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: The Messenger of Allah (may Allah bless him and grant him peace) said: "Indeed, a people will emerge from the Fire, having been touched by the scorching of the Fire as a punishment for sins they committed. Then Allah will surely bring them out by the grace of His mercy, and He will cause them to enter Paradise."
