17) باب لَنْ يَدْخُلَ أَحَدٌ الْجَنَّةَ بِعَمَلِهِ بَلْ بِرَحْمَةِ اللَّهِ تَعَالَى
وَحَدَّثَنَاهُ حَسَنٌ الْحُلْوَانِيُّ، حَدَّثَنَا يَعْقُوبُ بْنُ إِبْرَاهِيمَ بْنِ سَعْدٍ، حَدَّثَنَا عَبْدُ الْعَزِيزِ،
بْنُ الْمُطَّلِبِ عَنْ مُوسَى بْنِ عُقْبَةَ، بِهَذَا الإِسْنَادِ وَلَمْ يَذْكُرْ . " وَأَبْشِرُوا "
