Jabir reported Allah's Messenger (ﷺ) as saying:
وَحَدَّثَنَاهُ إِسْحَاقُ بْنُ إِبْرَاهِيمَ الْحَنْظَلِيُّ ، أَخْبَرَنَا عَبْدُ اللَّهِ بْنُ الْحَارِثِ ، عَنِ ابْنِ، جُرَيْجٍ أَخْبَرَنِي أَبُو الزُّبَيْرِ ، أَنَّهُ سَمِعَ جَابِرًا ، يُخْبِرُ عَنْ رَسُولِ اللَّهِ صلى الله عليه وسلم قَالَ " إِنْ كَانَ فِي شَىْءٍ فَفِي الرَّبْعِ وَالْخَادِمِ وَالْفَرَسِ " .
If bad luck were to be in anything, it is found in the land, in the servant and in the horse.
