وَحَدَّثَنَاهُ يَحْيَى بْنُ حَبِيبٍ الْحَارِثِيُّ ، حَدَّثَنَا خَالِدُ بْنُ الْحَارِثِ ، حَدَّثَنَا قُرَّةُ ، حَدَّثَنَا أَبُو الزُّبَيْرِ ، عَنْ جَابِرِ بْنِ عَبْدِ اللَّهِ ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " مَنْ يَصْعَدُ ثَنِيَّةَ الْمُرَارِ أَوِ الْمَرَارِ " . بِمِثْلِ حَدِيثِ مُعَاذٍ غَيْرَ أَنَّهُ قَالَ وَإِذَا هُوَ أَعْرَابِيٌّ جَاءَ يَنْشُدُ ضَالَّةً لَهُ .
He who would climb this hill of Murar. The rest of the hadith is the same but with this variation that it was a desert Arab who was finding out his lost thing.
