It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "The adulterer, when he commits adultery, is not a believer; the one who drinks wine, when he drinks it, is not a believer; and the thief, when he steals, is not a believer."
