Sahih Muslim Book 1, Hadith Number 169.

Chapter : He who dies associating none with Allah would enter Paradise and he who dies as a polytheist would enter the fire of Hell.

It is narrated on the authority of Jabir b. Abdullah: I heard the Messenger of Allah (may peace be upon him) saying: He who met Allah without associating anything with Allah entered Paradise and he who met Him associating (anything) with Him entered Fire.
