Hadith in Arabic:
وَعَنْ أَبِي سَلَمَةَ، سَمِعَ أَبَا هُرَيْرَةَ، بَعْدُ يَقُولُ قَالَ النَّبِيُّ صلى الله عليه وسلم “ لاَ يُورِدَنَّ مُمْرِضٌ عَلَى مُصِحٍّ ”. وَأَنْكَرَ أَبُو هُرَيْرَةَ حَدِيثَ الأَوَّلِ قُلْنَا أَلَمْ تُحَدِّثْ أَنَّهُ لاَ عَدْوَى فَرَطَنَ بِالْحَبَشِيَّةِ. قَالَ أَبُو سَلَمَةَ فَمَا رَأَيْتُهُ نَسِيَ حَدِيثًا غَيْرَهُ.
