If anyone sees a dream which he does not like, he should spit on his left side three times, and seek refuge with Allah from the Satan three times, and let him turn over from the side on which he was sleeping.
The Book of Dreams - Sahih Muslim 2262
This commentary examines the Prophetic guidance regarding unpleasant dreams from the perspective of classical Islamic scholarship.
The Nature of Dreams in Islam
Dreams are of three types: true dreams from Allah, disturbing dreams from Satan, and dreams arising from one's own thoughts. The hadith addresses the second category - dreams that cause distress and unease.
Spitting Lightly to the Left
The act of spitting lightly (without saliva) three times to the left symbolizes rejection of Satan's whispers, as the left side is traditionally associated with impurity and evil in Islamic tradition.
Seeking Refuge from Satan
Reciting "A'udhu billahi min ash-shaytan ir-rajim" three times reinforces spiritual protection and acknowledges that disturbing dreams are from Satan's deception.
Changing Sleeping Position
Turning to the other side physically demonstrates rejection of the dream's negative influence and prevents Satan from continuing his disturbance in the same state.
Scholarly Wisdom
Classical scholars emphasize that one should not share such dreams with others, as this may amplify their negative effect. The prescribed actions nullify Satan's influence and prevent the dream from manifesting negatively.
