Musannaf Ibn Abi Shayba 27:130

Ibn Fudayl narrated to us, from ‘Ata’, from Sa‘id ibn Jubayr, who said: When Allah revealed, "May the hands of Abu Lahab be ruined," the wife of Abu Lahab came to the Prophet, may Allah bless him and grant him peace, and Abu Bakr was with him. Abu Bakr said, "O Prophet of Allah, she is a woman with a foul tongue." He said, "She will be prevented from seeing me." He said: She did not see him. She said to Abu Bakr, "Your companion has satirized us." He said, "By Allah, he does not speak poetry, nor does he compose it." She said, "You are indeed a believer [in him]." She then turned back and left. Abu Bakr said, "O Messenger of Allah, she did not see you." He said, "An angel remained between me and her, shielding me until she went away."
