The Book of Faith (Kitab Al-Iman)

Muslim :: Book 1 : Hadith 167

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 (may peace be upon him) 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.
