It is narrated from Sayyiduna Jabir (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: Whoever meets Allah in such a state that he does not associate anyone with Him, he will enter Paradise. And whoever dies in such a state that he associates someone with Allah, he will enter Hell.
