Musnad Ahmad 31:105

Ishaq ibn Isa narrated to us, Abd al-Rahman ibn Zayd narrated to us, from his father, from Ata ibn Yasar, from Abu Hurayrah, who said: We were sitting writing what we heard from the Prophet, may Allah bless him and grant him peace, when he came out to us and said, "What is this that you are writing?" We said, "What we hear from you." He said, "A book alongside the Book of Allah?" We said, "What we hear." He said, "A book other than the Book of Allah? Purify the Book of Allah and make it exclusive." He said: So we gathered what we had written in one place, then we burned it with fire. We said, "O Messenger of Allah, may Allah bless him and grant him peace, shall we narrate from you?" He said, "Yes, narrate from me, and there is no harm. But whoever lies about me intentionally, let him take his seat in the Fire." He said: We said, "O Messenger of Allah, shall we narrate from the Children of Israel?" He said, "Yes, narrate from the Children of Israel, and there is no harm, for you do not narrate anything from them but that there was something even more amazing than it among them."
