I heard my uncle Ali ibn Musa Al-Ridha (s) narrate on the authority of his father (s), on the authority of his grandfather (s), on the authority of the Commander of the Faithful (s) that God’s Prophet (s) said, ‘Anyone who adopts a religion without hearing what he must hear would be condemned to destruction by God. Whoever adopts a religion through means other than what the Honorable the Exalted God has provided for His creatures, is a polytheist. The trustworthy means to adopt a religion is to follow the Blessed the Sublime God’s revelations to Muhammad (s).”
