Musnad Ahmad 937:150

Muhammad ibn Ja'far narrated to us, Shu'bah narrated to us, from Sulayman, from al-Mundhir al-Thawri, from some of their elders, from Abu Dharr, who said: "The Messenger of Allah, peace and blessings of Allah be upon him, left us, and there was not a bird flapping its wings in the sky except that he had mentioned to us some knowledge regarding it."
