حَدَّثَنَا زِيَادُ بْنُ أَيُّوبَ، حَدَّثَنَا يَزِيدُ بْنُ هَارُونَ، أَخْبَرَنَا الْوَلِيدُ بْنُ جَمِيلٍ، عَنِ الْقَاسِمِ أَبِي عَبْدِ الرَّحْمَنِ، عَنْ أَبِي أُمَامَةَ الْبَاهِلِيِّ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ ‏‏ ‏.‏ هَذَا حَدِيثٌ غَرِيبٌ مِنْ حَدِيثِ أَبِي أُمَامَةَ ‏.‏ "‏ مَنْ صَامَ يَوْمًا فِي سَبِيلِ اللَّهِ جَعَلَ اللَّهُ بَيْنَهُ وَبَيْنَ النَّارِ خَنْدَقًا كَمَا بَيْنَ السَّمَاءِ وَالأَرْضِ ‏"
