Re: kaala jaadu
The different between Nazar, Jadu and Jin, there are few signs but having those does not means someone is really have those (there could be medical issues people mistook for these).
Brifely in case of Nazar one would always feel lost of appetite, feels like burping.
Jaadu one would feel tired and lethargic, having regular headache and feel too much sleepily.
In case of Jinn one would have difficulty sleeping, sometime having pains in various part of body, like back and legs, would become short temper, in some cases they would have difficulty maintaing relationship.
Once again these are too much general symptoms, there is quite possible someone have these symptoms due to medical or psychological reason. Only experts could find out For sure(never take whatever they says as gospal truth,you can only trust those with 60%).
That ayata of Surah Alqalam are for Nazar only, but for Jadu and Protection from jinns you need to make a point to read MANZIL without fail every night before going to bed, same you need to DAM on the water and for drinking. Also make sure also dam on your self before going to bed.
Everyone of your family can share the water.
I hope this would help.
