Respected scholars, as-salamu `alaykum.
What is the teaching of Islam concerning palmistry? Is palmistry a truth or falseness? Are we allowed to practice it or to visit a palmist?
Jazakum Allahu khayran.
Answer (Sheikh Ahmad Kutty) :
Wa `alaykum as-salam wa rahmatullahi wa barakatuh.
In the Name of Allah, Most Gracious, Most Merciful.
All praise and thanks are due to Allah, and peace and blessings be upon His Messenger.
Dear sister in Islam, we commend your pursuit of knowledge and your keenness to seek what is lawful and to avoid what is not. We earnestly implore Allah so that He would save us all from the traps of Satan and enlighten our hearts with the light of Islam.
As far as the Islamic Shari`ah is concerned, it is forbidden for us to consult a so-called fortune-teller or astrologer. As Muslims, we believe that no one but Almighty Allah can have knowledge of the unseen. Full and accurate knowledge of the future is possessed only by Allah, All-Knowing, Who said in the Qur'an, (No soul knows what it will earn on the morrow) (Luqman 31:34).
In response to your question, Sheikh Ahmad Kutty, senior lecturer and Islamic scholar at the Islamic Institute of Toronto, Canada, stated,
Palmistry is not a science; it is simply based on guesswork and speculation about the future without any scientific basis. Islam is opposed to it, just as it is opposed to all forms of superstitions and irrational practices.
There are so many ills associated with palmistry: It breeds laziness and sloth and encourages charlatans to exploit the gullible and credulous people. One of the prayers of Prophet Muhammad (peace and blessings be upon him) was the following: "O Allah, I seek refuge in You from helplessness, laziness, cowardice, and miserliness."
Because palmistry entails speaking of Al-Ghayb (things exclusively known by Allah) based on mere guesswork, it is contrary to tawheed (belief in the Oneness of Allah), which is the cornerstone of Islam. Therefore, the Prophet (peace and blessings be upon him) warned the faithful against indulging in such practices. He said, "Whoever visits a foreteller [which includes palmists, tarot readers, etc.] and believes in his [or her] words has denied what was revealed to Muhammad [i.e. the Qur'an]."
He also said, "Whoever goes to a fortune-teller and asks him [or her] about something and then believes in his [or her] words will have his [or her] Prayer rejected for 40 days." May Allah help us safeguard our faith against the actions that undermine or diminish it in any way. Amen.
