البيهقي:٧٧٠٨أَخْبَرَنَا أَبُو الْحَسَنِ بْنُ أَبِي الْمَعْرُوفِ الْفَقِيهُ أنبأ أَبُو سَعِيدٍ عَبْدُ اللهِ بْنُ مُحَمَّدِ بْنِ عَبْدِ الْوَهَّابِ الرَّازِيُّ ثنا مُحَمَّدُ بْنُ أَيُّوبَ ثنا مُسْلِمٌ ثنا هِشَامٌ ثنا قَتَادَةُ

عَنِ الْحَسَنِ الْبَصْرِيِّ فِي زَكَاةِ رَمَضَانَ عَلَى مَنْ صَامَ صَاعُ تَمْرٍ أَوْ صَاعُ بُرٍّ
