Musnad Abu Ya'la al-Mawsili 150:395

Suwayd ibn Sa'id narrated to us, Salih ibn Musa narrated to us, from Mu'awiyah ibn Ishaq, from 'A'ishah bint Talhah, from 'A'ishah, the Mother of the Believers, who said: "By Allah, I was in my house one day, and the Messenger of Allah (may Allah bless him and grant him peace) was in the courtyard with his companions, and there was a curtain between me and them. Then Abu Bakr approached. The Prophet (may Allah bless him and grant him peace) said: 'Whoever is pleased to look at a man freed from the Fire, let him look at Abu Bakr.' And indeed, the name which his family gave him was 'Abdullah ibn 'Uthman, but the name 'Atiq (the freed one) prevailed over him."
