Sunan an-Nasa'i Book 48, Hadith 24
"According to whose recitation do you want me to recite? Because I recited seventy-odd Surahs to the Messenger of Allah when Zaid had two braids, and was playing with the other boys."
"I have never seen any man more handsome in a red Hullah than the Messenger of Allah ." He said: "And I saw his long hair, coming almost to his shoulders."
"Ibn Mas'ud addressed us and said: 'How do you want me to recite? According to the recitation of Zaid bin Thabit, when I learned seventy-odd Surahs from the mouth of the Messenger of Allah while Zaid was with the other boys with two braids?'"
