حَدَّثَنَا أَحْمَدُ بْنُ مَنِيعٍ، حَدَّثَنَا سُفْيَانُ بْنُ عُيَيْنَةَ، عَنْ عَبْدِ الْكَرِيمِ أَبِي أُمَيَّةَ، عَنْ عَبْدِ اللَّهِ بْنِ الْحَارِثِ، قَالَ زَوَّجَنِي أَبِي فَدَعَا أُنَاسًا فِيهِمْ صَفْوَانُ بْنُ أُمَيَّةَ فَقَالَ إِنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ ‏"‏ انْهَسُوا اللَّحْمَ نَهْسًا فَإِنَّهُ أَهْنَأُ وَأَمْرَأُ ‏"‏ ‏.‏ قَالَ وَفِي الْبَابِ عَنْ عَائِشَةَ وَأَبِي هُرَيْرَةَ ‏.‏ قَالَ أَبُو عِيسَى وَهَذَا حَدِيثٌ حَسَنٌ لاَ نَعْرِفُهُ إِلاَّ مِنْ حَدِيثِ عَبْدِ الْكَرِيمِ ‏.‏ وَقَدْ تَكَلَّمَ بَعْضُ أَهْلِ الْعِلْمِ فِي عَبْدِ الْكَرِيمِ الْمُعَلِّمِ مِنْهُمْ أَيُّوبُ السَّخْتِيَانِيُّ مِنْ قِبَلِ حِفْظِهِ ‏.‏

Narrated 'Abdullah bin Al-Harith: "My father had me married so he invited people, and Safwan bin Umayyah was among them. So he said: 'Indeed the Messenger of Allah (PBUH) said: 'Bite the meat (with your teeth) for indeed it is more enjoyable and more wholesome. He said: There are narration on this topic from 'Aishah and Abu Hurairah. [Abu 'Eisa said:] We do not know of this Hadith except through the narration of 'Abdul-Karim. Some of the people of knowledge have criticized 'Abdul-Karim Al-Mu'allim because of his memory, Ayyub As-Sakhtiyani was among them. Translation Not Available
