CAUSE AND AFFECT: When we hit a mirror it breaks, the cause is “hitting.” There can be many causes of a reaction (breaking) of a mirror. Diagnosis (known cause) through symptoms (affects) helps us through patient care & treatment. Cancer is the reason of many underlying dis-eases. "Unregulated cell growth" is an affect of many chain reactions in the genes. Fever is an affect from a throat infection, from any inflammation in the body. It is an overall response from the body's immune system. Infiltration of toxins, germs and body heals itself as an indication that it is invaded. For example, if we eat spicy food we feel acidity in our esophagus, hence, acidity is the effect of the cause (presence of spicy triggers)  Body produces physical symptoms but the cause can be different.
FOR EXAMPLE, PATIENTS COMING WITH SUCH SYMPTOMS AS: (which mainly do not respond to any medical treatment)

1. Physical pain moving from one area to another
2. Heaviness on shoulders
3. Tingling or crawling sensation on the skin
4. Pain in stomach & want to throw up
5. Brain fog, confusion, depression, anxiety
6. Palpitations, irregular heartbeat
7. Lack of focus (despite having a wonderful IQ)
8. Medicines do not respond, Brain depressants or muscle relaxants do not work
9. Ultrasounds and X-rays are normal

These are indications of spiritual problems.
WHAT IS POSSESSION?
Allah has given jinns 2 permissions. Shaytan can affect the heart, body & mind but CANNOT FULLY OPERATE IT. It can cause a defect in these but not fully operate it. For example, Laptop when infected with a virus, it can boggle the CPU.
SYMPTOMS & REACTIONS:
Sleep interruption (the jinn can interfere between body and mind's sensory pathways & release such hormones from the brain (medulla, hypothalamus) which gives a signal to the brain that body is very fresh, do not let it rest (sleep). But the sooner the patient listens to Quran or starts reciting Quran, he feels sleepy. Or the sooner Fajr time is near, he falls asleep.
Abnormal Body Temperature Brain’s thermostat becomes abnormal, feet or hands warm up. Thermometer does not show high temperatures.
Itching does not go away. Private parts get itchy. Because shaytan can circulate in our blood vessels. Where ever blood flows, jinns can have an affect there. They can cause abnormal release of neurotransmitters and cause abnormal reactions.
Stiffness Legs get stiff: similar to paralysis attacks. Many Sleep Apneas are caused by jinns.
Shoulders getting heavy
Memory Concentration Issues: Brain fog, cannot remember groceries (anyone who has jinn issues will not remember even a single item on the list, totally wipes out of short term memory. It can suddenly appear & disapper) This symptom does not respond to medications. All medical tests are normal. The problem of lack of concentrate despite of possessing an amazing intelligence and memory.
Eyesight Sometimes, vision gets blurry & foggy. If the nerves are deteriorating due to a medical reason, this happens slowly over time. But in jinn issues, in some span of time the patient can see vividly, clearly like a sharp eye sighted person, other times his vision suddenly drops, becomes opaque. There is no pattern in this degeneration of vision.
HEART SYMPTOMS
Nervousness (Hesitation) ghabrahat; These are symptoms of those people who have amazing mental health. These symptoms do not occur in a psychologically ill person.
Extreme Emotions Anger, sadness, aggression, extreme emotions which are involuntary.
Divine Thoughts, Atheist thoughts about Allah; Very wrong thoughts about Allah ans Islam (to kill your children, “I do not want to be an atheist but these waswas are killing me, I am thinking about Allah, what I do not want to think” “I am forced to think about atheism”
Parallel Thinking Overthinking and extreme whispering. Stress, depression, parallel thinking. Focus becomes hard for example, imagine a room in which you are trying to work or read a book, but there is television noise at the background. A jinn possessed person is constantly in this “noise zone,” thinking which he doesn’t want to hear. Noise is constantly being played at the back of his mind. Atheism ideas, filthy evil thoughts about Quran & Muhammad Salalahu Alayhe Wasalam. Regardless of all Brain tests are normal, the patient is diagnosed with Schizophrenia. Hallucination symptoms are normal, even though brain functions are perfectly working fine. With all Brain tests being normal.
Talking in Sleep, sleep walking
SYMPTOMS IN BODY
Numbness in body (this is different to a normal numbness on sitting for a long time)
Palpitation / Flicking, trembling. Sometimes feels like an area of the body is throbbing, flickering, triggered by recitation of Quran.
Burning in the Body
Internal Pinning
Miscarriages are common.
Abnormal Menstrual cycle Jinaat hate human generations and to stop baby conception, jinns kick the ovaries of a Muslim women, they try their best to exterminate her pregnancy. They can block blood from a fetus. Menses are good for a woman; it shows she can reproduce children. PCOS maybe a sign of jinn inflicted PCOS.
Stomach Stiffness Constipation Cannot pass stool for 10 days, yet still feels hungry. Senna leaves work here.
Headache & Nausea on listening to Quran.  
PARANORMAL ACTIVITIES

1. Shadows in the homes, they feel presence of someone. They feel someone has bit them, or a black shadow might linger here and there.
2. On reciting Quran, they can smell stuff, very strong sense of smell. (Pleasant or stingy or dirty)
3. Cloths are found torn, as if someone tore them (sometimes Ashiq jinn)
4. Can see blood spots on their cloths (not always)
5. Jinns can sexually harass women too (in magic symptoms), erectile dysfunction (in men) are symptoms of jinn inflicted through magic.
