Zahdam Al-Jarmi RA.says that we were present in the assembly of abu Musa Ash'ari (may Allah be pleased with him). Fowl meat was served for food. A, person from among those present, moved back. Abu Musa Radiyalahu 'Anhu asked him the reason (for doing so). He replied 'I had seen the fowl eat something (dirty) so I swore an oath that I will not eat it'. Abu Musa (may Allah be pleased with him) said:
'In that case, I had seen Messenger of Allah ﷺ eat the meat of a fowl' (come and partake of it without fear. If it was not permissible or disliked, how did Messenger of Allah ﷺ eat it).
حَدَّثَنَا هَنَّادٌ، حَدَّثَنَا وَكِيعٌ، عَنْ سُفْيَانَ، عَنْ أَيُّوبَ، عَنْ أَبِي قِلابَةَ، عَنْ زَهْدَمٍ الْجَرْمِيِّ، قَالَ: كُنَّا عِنْدَ أَبِي مُوسَى الأَشْعَرِيِّ، فَأُتِيَ بِلَحْمِ دَجَاجٍ فَتَنَحَّى رَجُلٌ مِنَ الْقَوْمِ، فَقَالَ: مَا لَكَ؟ فَقَالَ: إِنِّي رَأَيْتُهَا تَأْكُلُ شَيْئًا فَحَلَفْتُ أَنْ لا آكُلَهَا.
