Some chicken was brought to Abu Musa and a man moved away from the people. He said: "What is the matter with you?" He said: "I saw it eating something that I consider filthy, and I swore I would not eat it." Abu Musa said: "Come and eat, for I saw the Messenger of Allah eating it." And he told him to offer an expiation for his vow (Kafarat Al-Yamin)  

أَنَّ أَبَا مُوسَى أُتِيَ بِدَجَاجَةٍ فَتَنَحَّى رَجُلٌ مِنَ الْقَوْمِ فَقَالَ مَا شَأْنُكَ قَالَ إِنِّي رَأَيْتُهَا تَأْكُلُ شَيْئًا قَذِرْتُهُ فَحَلَفْتُ أَنْ لاَ آكُلَهُ فَقَالَ أَبُو مُوسَى ادْنُ فَكُلْ فَإِنِّي رَأَيْتُ رَسُولَ اللَّهِ ﷺ يَأْكُلُهُ وَأَمَرَهُ أَنْ يُكَفِّرَ عَنْ يَمِينِهِ  

"We were with Abu Musa and His food was brought, including chicken. Among the people there was a man from banu Taimullah who had reddish complexion, as if he were a freed slave. He did not come close and Abu Musa said: "Come (and eat) for I saw the Messenger of All eating it"'  

كُنَّا عِنْدَ أَبِي مُوسَى فَقُدِّمَ طَعَامُهُ وَقُدِّمَ فِي طَعَامِهِ لَحْمُ دَجَاجٍ وَفِي الْقَوْمِ رَجُلٌ مِنْ بَنِي تَيْمِ اللَّهِ أَحْمَرُ كَأَنَّهُ مَوْلًى فَلَمْ يَدْنُ فَقَالَ لَهُ أَبُو مُوسَى ادْنُ فَإِنِّي قَدْ رَأَيْتُ رَسُولَ اللَّهِ ﷺ يَأْكُلُ مِنْهُ  

on the Day of Khaibar, the Prophet of Allah forbade eating any birds with talons and any predators with fangs. (Daif)  

أَنَّ نَبِيَّ اللَّهِ ﷺ نَهَى يَوْمَ خَيْبَرَ عَنْ كُلِّ ذِي مِخْلَبٍ مِنَ الطَّيْرِ وَعَنْ كُلِّ ذِي نَابٍ مِنَ السِّبَاعِ
