In Islam, true dreams are "one-fortieth of prophecy." Prophet Muhammad classified dreams into three types: divine, demonic, and personal. A special prayer, Istikhara, asks God for guidance through sleep. And the world's longest continuously published dream dictionary is Islamic, over 1,300 years in print.
Islam takes dreams seriously: Prophet Muhammad taught that a true dream, ru'ya, is "one-fortieth of prophecy," and classified dreams into three kinds, the true dream from Allah, the false dream from Shaytan, and the dream that comes from a person's own mind. Guidance is drawn from the Qur'an, hadith, and scholars like Ibn Sirin, whose 8th-century dream book is still consulted today.

How to read this
This page describes how dreams are understood within Islam, drawn from the Qur'an, hadith, and the scholars the page cites, such as Ibn Sirin and Ibn Sina. It presents belief and tradition with respect. It does not adjudicate religious truth, and interpretations vary across schools and scholars.
Prophet Muhammad established one of the clearest dream classification systems in any religion. Three types of dreams exist: Ru'ya, a true, good dream sent by Allah. It is considered "one-fortieth of prophecy" and should be shared only with trusted people. Hulm, a false, disturbing dream from Shaytan (the devil), designed to frighten or mislead. The prescribed response is to spit lightly three times to the left and seek refuge in Allah. Hadith an-nafs, a dream from one's own mind, reflecting daily worries and desires.
This three-part classification resonates across traditions. Macrobius classified five dream types in Rome. The Talmud distinguished divine from mundane dreams. The core question is universal: which dreams matter, and which are noise? It is the same question modern dream science still debates.
"True dreams are one-fortieth of prophecy."
Hadith of Prophet Muhammad (Sahih al-Bukhari)Salat al-Istikhara is a special prayer performed when a Muslim faces a difficult decision, marriage, career, relocation, any crossroads. The person performs the prayer, then sleeps waiting for a dream that reveals the right path.
This is not ancient history, it is living practice. Hundreds of millions of Muslims worldwide perform Istikhara regularly. It represents one of the most widespread active dream practices on Earth today, connecting modern believers to a 1,400-year-old tradition of seeking divine guidance through sleep.
The practice has parallels in Egyptian temple incubation and Greek enkoimesis, all share the principle of deliberately seeking a meaningful dream through ritual preparation.
