حَدَّثَنَا هِشَامُ بْنُ عَمَّارٍ، حَدَّثَنَا أَنَسُ بْنُ عِيَاضٍ، حَدَّثَنَا عَبْدُ اللَّهِ بْنُ عَبْدِ الْعَزِيزِ اللَّيْثِيُّ، عَنِ الْمَقْبُرِيِّ، عَنْ أَبِي هُرَيْرَةَ، قَالَ: قَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ " مَنْ صَامَ يَوْمًا فِي سَبِيلِ اللَّهِ، زَحْزَحَ اللَّهُ وَجْهَهُ عَنِ النَّارِ سَبْعِينَ خَرِيفًا " .
