Musannaf Ibn Abi Shayba 3:3591

Waki’ narrated to us, from Yazid, from Ibn Sirin, from Mughira ibn Sulayman, from Ibn Umar, who said: I memorized ten rak'ahs from the Messenger of Allah, may Allah bless him and grant him peace. He then mentioned the like of the hadith of Ja’far, except that he did not say, "Hafsa narrated to me."
