Sunan an-Nasa'i, Volume 5, Book 42, Hadith 4325 (DarusSalam) ⓘ

It was narrated that Thabit bin Yazid Al-Ansari said: "We were with the Prophet on a journey. We stopped to camp and the people caught some mastigures. I took a mastigure and grilled it, and brought it to the Prophet. He took a palm stalk, and started counting his fingers with it, and said: 'A nation from among the children of Israel was turned into beasts of the Earth, and I do not know what kind of animals they were, I said: 'O Messenger of Allah, the people have eaten some of them.' He did not tell them to eat it, and he did not forbid them from eating it."

أَخْبَرَنَا سُلَيْمَانُ بْنُ مَنْصُورٍ الْبَلْخِيُّ، قَالَ حَدَّثَنَا أَبُو الأَحْوَصِ، سَلاَّمُ بْنُ سُلَيْمٍ عَنْ حُصَيْنٍ، عَنْ زَيْدِ بْنِ وَهْبٍ، عَنْ ثَابِتِ بْنِ يَزِيدَ الأَنْصَارِيِّ، قَالَ كُنَّا مَعَ رَسُولِ اللَّهِ صلى الله عليه وسلم فِي سَفَرٍ فَنَزَلْنَا مَنْزِلاً فَأَصَابَ النَّاسُ ضِبَابًا فَأَخَذْتُ ضَبًّا فَشَوَيْتُهُ ثُمَّ أَتَيْتُ بِهِ النَّبِيَّ صلى الله عليه وسلم فَأَخَذَ عُودًا يَعُدُّ بِهِ أَصَابِعَهُ ثُمَّ قَالَ ‏ "‏ إِنَّ أُمَّةً مِنْ بَنِي إِسْرَائِيلَ مُسِخَتْ دَوَابَّ فِي الأَرْضِ وَإِنِّي لاَ أَدْرِي أَىُّ الدَّوَابِّ هِيَ ‏" ‏ ‏.‏ قُلْتُ يَا رَسُولَ اللَّهِ إِنَّ النَّاسَ قَدْ أَكَلُوا مِنْهَا - قَالَ - فَمَا أَمَرَ بِأَكْلِهَا وَلاَ نَهَى ‏.‏
