It was narrated that Abu Sa’eed Al-Khudri said:“A man from among Ahlus-Suffah called the Messenger of Allah (ﷺ) when he had finished the prayer, saying: ‘O Messenger of Allah! Our land is a land infested with mastigures. What do you think of (eating) mastigures?’ He said: ‘I have heard that a nation was transformed.’ He did not tell us to eat them, and he did not forbid that.”
