الترمذي:٦٧٤حَدَّثَنَا عُقْبَةُ بْنُ مُكْرَمٍ الْبَصْرِيُّ حَدَّثَنَا سَالِمُ بْنُ نُوحٍ عَنِ ابْنِ جُرَيْجٍ عَنْ عَمْرِو بْنِ شُعَيْبٍ عَنْ أَبِيهِ عَنْ جَدِّهِ

أَنَّ النَّبِيَّ ﷺ بَعَثَ مُنَادِيًا فِي فِجَاجِ مَكَّةَ أَلاَ إِنَّ صَدَقَةَ الْفِطْرِ وَاجِبَةٌ عَلَى كُلِّ مُسْلِمٍ ذَكَرٍ أَوْ أُنْثَى حُرٍّ أَوْ عَبْدٍ صَغِيرٍ أَوْ كَبِيرٍ مُدَّانِ مِنْ قَمْحٍ أَوْ سِوَاهُ صَاعٌ مِنْ طَعَامٍ  

قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ غَرِيبٌ وَرَوَى عُمَرُ بْنُ هَارُونَ هَذَا الْحَدِيثَ عَنِ ابْنِ جُرَيْجٍ وَقَالَ عَنِ الْعَبَّاسِ بْنِ مِينَاءَ عَنِ النَّبِيِّ ﷺ فَذَكَرَ بَعْضَ هَذَا الْحَدِيثِ حدثنا جارود حدثنا عمر بن هارون هذا الحديث
