Mentioning the Differences in the Reports from Yahya bin Abi Kathir and An-Nadr bin Shaiban
أَخْبَرَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ، قَالَ أَنْبَأَنَا النَّضْرُ بْنُ شُمَيْلٍ، قَالَ أَنْبَأَنَا الْقَاسِمُ بْنُ الْفَضْلِ، قَالَ حَدَّثَنَا النَّضْرُ بْنُ شَيْبَانَ، عَنْ أَبِي سَلَمَةَ، فَذَكَرَ مِثْلَهُ وَقَالَ مَنْ صَامَهُ وَقَامَهُ إِيمَانًا وَاحْتِسَابًا .
A similar report was narrated from Abu Salamah and he said: "Whoever fasts it and spends its nights in prayer out of faith and in the hope of reward." (Daif)
