The Book of Faith
The evidence that the one who dies not associating anything with Allah will enter paradise, and the one who dies as idolator will enter the fire
وَحَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، وَأَبُو كُرَيْبٍ قَالاَ حَدَّثَنَا أَبُو مُعَاوِيَةَ، عَنِ الأَعْمَشِ، عَنْ أَبِي سُفْيَانَ، عَنْ جَابِرٍ، قَالَ أَتَى النَّبِيَّ صلى الله عليه وسلم رَجُلٌ فَقَالَ يَا رَسُولَ اللَّهِ مَا الْمُوجِبَتَانِ فَقَالَ مَنْ مَاتَ لاَ يُشْرِكُ بِاللَّهِ شَيْئًا دَخَلَ الْجَنَّةَ وَمَنْ مَاتَ يُشْرِكُ بِاللَّهِ شَيْئًا دَخَلَ النَّارَ .
It is narrated on the authority of Jabir that a man came to the Messenger of Allah (ﷺ) and said: Messenger of Allah, what are the two things quite unavoidable? He replied: He who dies without associating anyone with Allah would (necessarily) enter Paradise and he who dies associating anything with Allah would enter the (Fire of) Hell.
