The Book of Faith
1/4. Chapter:
Explaining the faith by means of which a person is admitted into paradise, and that the one who adheres to what is enjoined upon him will enter paradise
Sahih Muslim
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، وَأَبُو كُرَيْبٍ - وَاللَّفْظُ لأَبِي كُرَيْبٍ - قَالاَ حَدَّثَنَا أَبُو مُعَاوِيَةَ، عَنِ الأَعْمَشِ، عَنْ أَبِي سُفْيَانَ، عَنْ جَابِرٍ، قَالَ أَتَى النَّبِيَّ صلى الله عليه وسلم النُّعْمَانُ بْنُ قَوْقَلٍ فَقَالَ يَا رَسُولَ اللَّهِ أَرَأَيْتَ إِذَا صَلَّيْتُ الْمَكْتُوبَةَ وَحَرَّمْتُ الْحَرَامَ وَأَحْلَلْتُ الْحَلاَلَ أَأَدْخُلُ الْجَنَّةَ فَقَالَ النَّبِيُّ صلى الله عليه وسلم " نَعَمْ " .
It is narrated on the authority of Jabir that Nu'man b. Qaufal came to the Prophet (ﷺ) and said: Would I enter Paradise if I say the obligatory prayers and deny myself that which is forbidden and treat that as lawful what has been made permissible (by the Shari'ah)? The Prophet (ﷺ) replied in the affirmative.
