Chapter 16: What Has Been Related About The One Who Accuses His Brother Of Disbelief - كتاب الإيمان عن رسول الله صلى الله عليه وسلم
حَدَّثَنَا قُتَيْبَةُ، عَنْ مَالِكِ بْنِ أَنَسٍ، عَنْ عَبْدِ اللَّهِ بْنِ دِينَارٍ، عَنِ ابْنِ عُمَرَ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ " أَيُّمَا رَجُلٍ قَالَ لأَخِيهِ كَافِرٌ فَقَدْ بَاءَ بِهِ أَحَدُهُمَا " . هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ غَرِيبٌ . وَمَعْنَى قَوْلِهِ بَاءَ يَعْنِي أَقَرَّ .
