Musnad Abu Ya'la al-Mawsili 152:270

Abu Khaythama narrated to us, al-Hasan ibn Musa narrated to us, Hammad narrated to us, from ‘Ata’ ibn al-Sa’ib, from ‘Amr ibn Maymun, that Ibn Mas’ud narrated to them that the Messenger of Allah (may Allah bless him and grant him peace) said: "There will be people in the Fire for as long as Allah wills, then Allah will have mercy on them, and they will be in the lowest part of Paradise. They will be washed in the River of Life, and the people of Paradise will call them 'the Hell-dwellers.' If one of them were to host the world, he would feed them, give them drink, provide them with bedding, cover them, and—I think he said—marry them off, without that diminishing anything from him."
