حَدَّثَنَا مَحْمُودُ بْنُ غَيْلاَنَ، حَدَّثَنَا أَبُو دَاوُدَ الطَّيَالِسِيُّ، عَنْ شُعْبَةَ، أَخْبَرَنِي سِمَاكُ بْنُ حَرْبٍ، قَالَ سَمِعْتُ قَبِيصَةَ بْنَ هُلْبٍ، يُحَدِّثُ عَنْ أَبِيهِ، قَالَ سَأَلْتُ النَّبِيَّ صلى الله عليه وسلم عَنْ طَعَامِ النَّصَارَى فَقَالَ " لاَ يَتَخَلَّجَنَّ فِي صَدْرِكَ طَعَامٌ ضَارَعْتَ فِيهِ النَّصْرَانِيَّةَ " . قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ .
