All perfect praise be to Allah Alone. May peace and blessing be upon the Noblest Prophet Muhammad, his Family, and Companions. Some people are widely known to rely on soothsayers, astrologers, diviners, and sorcerers to unveil the future, bring luck, fulfill marriage, succeed in exams, and other matters that are only known to Allah (Glorified and Exalted be He). Allah (Exalted be He) says: "(He Alone is) the AllKnower of the Ghaib (Unseen), and He reveals to none His Ghaib (Unseen)." Except to a Messenger (from mankind) whom He has chosen (He informs him of unseen as much as He likes), and then He makes a band of watching guards (angels) to march before him and behind him.
Say: "None in the heavens and the earth knows the Ghaib (Unseen) except Allâh, nor can they perceive when they shall be resurrected."
Sulaimân did not disbelieve, but the Shayâtîn (devils) disbelieved, teaching men magic and such things that came down at Babylon to the two angels, Hârût and Mârût, but neither of these two (angels) taught anyone (such things) till they had said, "We are only for trial, so disbelieve not (by learning this magic from us)." And from these (angels) people learn that by which they cause separation between man and his wife, but they could not thus harm anyone except by Allâh's Leave. And they learn that which harms them and profits them not. And indeed they knew that the buyers of it (magic) would have no share in the Hereafter. And how bad indeed was that for which they sold their ownselves, if they but knew.
That which they have made is only a magician's trick, and the magician will never be successful, to whatever amount (of skill) he may attain. He (Exalted be He) says: And We revealed to Mûsâ (Moses) (saying): "Throw your stick," and behold! It swallowed up straight away all the falsehoods which they showed. Thus truth was confirmed, and all that they did was made of no effect.
These Ayahs (Qur'anic verses) and others confirm the loss and evil end of the sorcerer in this life and the Hereafter. He never brings good and the magic he learns or teaches entails harm to the person who practices it. Moreover, Allah (may He be Praised) stated that the works of the sorcerers are of no effect.
Avoid the seven great destructive sins." The people enquired, "O Allah's Messenger! What are they?" He said: "To join others in worship along with Allah, to practice sorcery, to kill the life which Allah has forbidden except for a just cause (according to Islamic law), to eat up Riba (usury), to eat up an orphan's wealth, to give your back to the enemy and flee from the battlefield at the time of fighting, and to accuse chaste women, who never even think of anything touching chastity and are good believers, (of illicit relations). (Agreed upon by Imams AlBukhari and Muslim)
This Hadith emphasizes the gravity of the crime of practicing sorcery; hence, Allah mentioned it along with Shirk (associating others in worship with Allah) and informed us that it is a destructive sin. Sorcery is Kufr (disbelief) since a person does not excel in it except after committing acts of disbelief.
Some people asked Allah's Messenger (peace be upon him) about the fortunetellers and he said: ' They are nothing." They said, 'O Allah's Messenger, sometimes they tell us of a thing that turns out to be true." Allah's Messenger (peace be upon him) said, "A Jinn snatches that true word and pours it into the ear of his friend (the fortuneteller) (as one puts something into a bottle). The fortuneteller then mixes with that word one hundred lies." Related by AlBukhary.
