باب مَنْ أَشْرَكَ فِي عَمَلِهِ غَيْرَ اللَّهِ
Sahih Muslim 2987 b

Sufyan reported this hadith with the same chain of transmitters and he made this addition:

" I did not hear anyone saying besides him that it was Allah's Messenger (ﷺ) who had said so."
وَحَدَّثَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ، حَدَّثَنَا الْمُلاَئِيُّ، حَدَّثَنَا سُفْيَانُ، بِهَذَا الإِسْنَادِ وَزَادَ وَلَمْ أَسْمَعْ أَحَدًا غَيْرَهُ يَقُولُ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏.‏
