Musannaf Ibn Abi Shayba 28:914

Yazid ibn Harun narrated to us, he said: Sufyan ibn Husayn informed us, from Ali ibn Zayd, from Anas ibn Malik, who said: Al-Ukaydir gifted a jar of *mann* (manna) to the Messenger of Allah, may Allah bless him and grant him peace. He then began to distribute it among us.
