Sahih Muslim , Book 1, Hadith 167 (USC-MSA)

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 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.

حَدَّثَنَا مُحَمَّدُ بْنُ عَبْدِ اللَّهِ بْنِ نُمَيْرٍ، حَدَّثَنَا أَبِي وَوَكِيعٌ، عَنِ الأَعْمَشِ، عَنْ شَقِيقٍ، عَنْ عَبْدِ اللَّهِ، قَالَ وَكِيعٌ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم وَقَالَ ابْنُ نُمَيْرٍ سَمِعْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم يَقُولُ ‏ "‏ مَنْ مَاتَ يُشْرِكُ بِاللَّهِ شَيْئًا دَخَلَ النَّارَ ‏" ‏ ‏.‏ وَقُلْتُ أَنَا وَمَنْ مَاتَ لاَ يُشْرِكُ بِاللَّهِ شَيْئًا دَخَلَ الْجَنَّةَ ‏.‏
