Musnad Abu Ya'la al-Mawsili 151:86

Sa'id ibn al-Ash'ath narrated to us, al-Haytham ibn al-Shaddakh al-'Abdi informed me, from al-A'mash, who narrates from Yahya ibn Waththab, from 'Alqama ibn Qays, from 'Abdullah ibn Mas'ud, who said: "I am amazed at the people and their abandoning my recitation and taking the recitation of Zayd, when I have taken seventy surahs directly from the mouth of the Messenger of Allah (may Allah bless him and grant him peace). And Zayd ibn Thabit is a youth with a forelock, coming and going in Medina."
