Abu Mūsa al-Ash‘ari (may Allah be pleased with him) reported that the Messenger of Allah, peace be upon him, said: "Three will not enter Paradise: the habitual drinker of alcohol, the one who severs the ties of kinship, and the one who believes in sorcery. "
The Messenger of Allah (may Allah’s peace and blessings be upon him) informs us in this Hadīth that there are three categories of people who will not enter Paradise because of the major sins that they commit, all of which are harmful to themselves and the whole community: The first of them is the one involved in habitual drinking of alcohol, which obscures one's reason, magnanimity, and even humanity. The second is the one who breaks the ties of kinship, because in so doing, he causes enmity and disunity between the members of his family - the result of this may be that one would live by himself, outcast and ignored by the closest people to him. The third is the one who believes in sorcery, which also includes fortune-telling, because this encourages cheating, fraud, and deception for the purpose of stealing the money of the people. The threat here does not apply to the one who merely believes that sorcery has effect, because it undoubtedly has effect. Nevertheless, whoever believes that sorcery can transform the nature of things (transform wood into gold for example) is certainly meant by this threat because no one can do this except Allah, the Almighty.
