Characteristics of the Day of Judgment, Paradise, and Hell
كتاب صفة القيامة والجنة والنار
Chapter 17: 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 2818 b
This hadith has been narrated on the authority of Musa b. `Uqba with the same chain of transmitters and he did not make a mention of
"Be happy".وَحَدَّثَنَاهُ حَسَنٌ الْحُلْوَانِيُّ، حَدَّثَنَا يَعْقُوبُ بْنُ إِبْرَاهِيمَ بْنِ سَعْدٍ، حَدَّثَنَا عَبْدُ الْعَزِيزِ، بْنُ الْمُطَّلِبِ عَنْ مُوسَى بْنِ عُقْبَةَ، بِهَذَا الإِسْنَادِ وَلَمْ يَذْكُرْ " وَأَبْشِرُوا " .
