Sahih Muslim 675 b

This hadith has been narrated on the authority of Abu Huraira by another chain of transmitters up to the words:

" And cause them a famine like that (which broke out at the time) of Joseph," but the subsequent portion was not mentioned.
وَحَدَّثَنَاهُ أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، وَعَمْرٌو النَّاقِدُ، قَالاَ حَدَّثَنَا ابْنُ عُيَيْنَةَ، عَنِ الزُّهْرِيِّ، عَنْ سَعِيدِ بْنِ الْمُسَيَّبِ، عَنْ أَبِي هُرَيْرَةَ، عَنِ النَّبِيِّ صلى الله عليه وسلم إِلَى قَوْلِهِ ‏ "‏ وَاجْعَلْهَا عَلَيْهِمْ كَسِنِي يُوسُفَ ‏"‏ ‏.‏ وَلَمْ يَذْكُرْ مَا بَعْدَهُ ‏.‏
