Musnad Ahmad 1289:2

Ya'qub narrated to us, my father narrated to us, from Ibn Ishaq, Abdullah ibn Abi Bakr ibn Muhammad ibn 'Amr ibn Hazm narrated to me, from Yahya ibn Abdullah ibn Abd al-Rahman ibn Sa'd ibn Zurarah, from Umm Hisham bint Harithah, who said: "Our oven and the oven of the Prophet, may Allah bless him and grant him peace, were one for two years, or a year and part of a year. And I did not learn {Qaf. By the Glorious Qur'an} except from the tongue of the Messenger of Allah, may Allah bless him and grant him peace; he used to recite it every Friday upon the pulpit when he addressed the people."
