Chapter: No One Will Enter Paradise By Virtue Of His Deeds, Rather By The Mercy Of Allah, Exalted Is He

باب لَنْ يَدْخُلَ أَحَدٌ الْجَنَّةَ بِعَمَلِهِ بَلْ بِرَحْمَةِ اللَّهِ تَعَالَى ‏‏
Sahih Muslim 2817 b

A hadith like this has been narrated on the authority of A'mash through two other chains of transmitters. The wording is, however, the same.

حَدَّثَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ، حَدَّثَنَا جَرِيرٌ، عَنِ الأَعْمَشِ، بِالإِسْنَادَيْنِ جَمِيعًا كَرِوَايَةِ ابْنِ نُمَيْرٍ ‏.‏
