I heard Ibn Abi Awfa say when I asked him about (eating) locusts: I went on six or seven expeditions along with the Messenger of Allah (ﷺ) and we ate them (locusts) along with him.
Sunan Abi Dawud Book 28, Hadith 77
← Previous Hadith On the day of Khaybar the Messenger of Allah (may pease be upon him) forbade (eating) the flesh of domestic asses, and the animal which feeds on filth: riding it and eating its flesh.

Sunan Abi Dawud Book 28, Hadith 76 Next Hadith → The Messenger of Allah (ﷺ) was asked about (eating) locusts. He replied: They are the most numerous of Allah's hosts. I neither eat them nor declare them unlawful.
