Musnad Abu Ya'la al-Mawsili 115:213

Zuhayr narrated to us, Rawh ibn ‘Ubadah narrated to us, Hisham ibn Abi ‘Abd Allah narrated to us, from Qatadah, from Anas, that the Prophet of Allah (may Allah bless him and grant him peace) said: "People will certainly be afflicted by the scorching of the Fire as a punishment for sins they committed. Then Allah will admit them into Paradise by the grace of His mercy. They will be called 'the Jahannamiyyun' (the Hell-dwellers)."
