Take a piece of paper and write
ي اح ق ي ا ق ه ا ر
then read and blow on it surah Fatiha with Bismillah, preferably joining the meem with the laam of Alhamdu
Also read once and blow
وإن يكاد الذين كفروا ليزلقونك بأبصارهم لما سمعوا الذكر ويقولون إنه لمجنون وما هو إلا ذكر للعالمين
Then pass the paper over the patient from head to toe seven times and burn it.
Preferably do this for 3 or 7 nights consecutively.
