حَدَّثَنِي عَبْدُ اللَّهِ بْنُ مُحَمَّدٍ، حَدَّثَنَا أَبُو عَامِرٍ، حَدَّثَنَا هَمَّامٌ، عَنْ أَبِي جَمْرَةَ الضُّبَعِيِّ، قَالَ كُنْتُ أُجَالِسُ ابْنَ عَبَّاسٍ بِمَكَّةَ، فَأَخَذَتْنِي الْحُمَّى، فَقَالَ أَبْرِدْهَا عَنْكَ بِمَاءِ زَمْزَمَ، فَإِنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ ‏"‏ الْحُمَّى مِنْ فَيْحِ جَهَنَّمَ فَأَبْرِدُوهَا بِالْمَاءِ ‏"‏‏.‏ أَوْ قَالَ ‏"‏ بِمَاءِ زَمْزَمَ ‏"‏‏.‏ شَكَّ هَمَّامٌ‏.‏
