Musnad Abu Ya'la al-Mawsili 159:7

Abu Bakr narrated to us, Abu Abd al-Rahman narrated to us, from Sa'id ibn Abi Ayyub, who said: Ja'far ibn Rabi'ah informed me, from al-A'raj, from Abu Hurayrah, from the Prophet (may Allah bless him and grant him peace), who said: "When you hear the crowing of roosters, then they have seen an angel, so ask (Allah) and beseech Him. And when you hear the braying of a donkey, then it has seen a devil, so seek refuge in Allah from the evil of what it has seen."
