Musnad Ahmad 289:8

Muhammad ibn Ja'far narrated to us, Shu'bah narrated to us, from Ya'la ibn 'Ata, from Waki' ibn 'Udas, from Abu Razin, his uncle, who said: I said: "O Messenger of Allah, where is my mother?" He said: "Your mother is in the Fire." He said: "I said: 'Then where are those of your family who have passed away?'" He said: "Are you not pleased that your mother should be with my mother?" My father said: "The correct [name] is 'Udas."
