بَاب النَّهْيِ عَنْ صَوْمِ الدَّهْرِ لِمَنْ تَضَرَّرَ بِهِ أَوْ فَوَّتَ بِهِ حَقًّا أَوْ لَمْ يُفْطِرْ الْعِيدَيْنِ وَالتَّشْرِيقَ وَبَيَانِ تَفْضِيلِ صَوْمِ يَوْمٍ وَإِفْطَارِ يَوْمٍ

وَحَدَّثَنِيهِ مُحَمَّدُ بْنُ حَاتِمٍ، حَدَّثَنَا مُحَمَّدُ بْنُ بَكْرٍ، أَخْبَرَنَا ابْنُ جُرَيْجٍ، بِهَذَا الإِسْنَادِ وَقَالَ إِنَّ أَبَا الْعَبَّاسِ الشَّاعِرَ أَخْبَرَهُ . قَالَ مُسْلِمٌ أَبُو الْعَبَّاسِ السَّائِبُ بْنُ فَرُّوخَ مِنْ أَهْلِ مَكَّةَ ثِقَةٌ عَدْلٌ .
