(40) باب مَنْ مَاتَ لاَ يُشْرِكُ بِاللَّهِ شَيْئًا دَخَلَ الْجَنَّةَ وَمَنْ مَاتَ مُشْرِكًا دَخَلَ النَّارَ
It is narrated on the authority of Abdullah b. Mas'ud that Waki told (him) that the Messenger of Allah had observed and Ibn Numair asserted:
I heard the Messenger of Allah (ﷺ) saying: He who dies associating anything with Allah would enter the Fire (of Hell). 'Abdullah b. Mas'ud said: I say that he who died without associating anything with Allah entered Paradise.
