"I entered upon Abu Musa while he was eating chicken, and he said: 'Sit and eat, for indeed I saw the Messenger of Allah (ﷺ) eating it.'" [Abu 'Eisa said:] This Hadith is Hasan. This Hadith has been reported through other routes from Zahdam, and we do not know of it except as the narration of Zahdam. (One of the narrators) Abu Al-'Awwam is 'Imran Al-Qattan.
حَدَّثَنَا زَيْدُ بْنُ أَخْزَمَ الطَّائِيُّ، حَدَّثَنَا أَبُو قُتَيْبَةَ، عَنْ أَبِي الْعَوَّامِ، عَنْ قَتَادَةَ، عَنْ زَهْدَمٍ الْجَرْمِيِّ، قَالَ دَخَلْتُ عَلَى أَبِي مُوسَى وَهُوَ يَأْكُلُ دَجَاجًا فَقَالَ ادْنُ فَكُلْ فَإِنِّي رَأَيْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم يَأْكُلُهُ . قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ . وَقَدْ رُوِيَ هَذَا الْحَدِيثُ مِنْ غَيْرِ وَجْهٍ عَنْ زَهْدَمٍ وَلاَ نَعْرِفُهُ إِلاَّ مِنْ حَدِيثِ زَهْدَمٍ . وَأَبُو الْعَوَّامِ هُوَ عِمْرَانُ الْقَطَّانُ .
