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.
Sunan Abi Dawud Book 28, Hadith 78
← Previous Hadith 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 Next Hadith → Salman said: The Messenger of Allah(ﷺ) was asked about locusts. He replied in a similar way(as mentioned above) saying: The most numerous of Allah’s host. The narrator ‘Ali said: His name is Fa’id, that is the name of al-Awwam.

Abu Dawud said: This tradition has been transmitted by Hammad b. Salamah, from Abu al-Awwam from Abu uthman, from the Prophet (ﷺ). He did not mention salman (i.e., the companions).
