I have got lot of things to say about them...... I had personal experience as I have seen some things at friends place.
1st One
During Ramdaan before 8 or 9 years, I was in teens, I had insisted on staying in Masjid for Eatiqaf,,,. It was winter and snowy, and I was alone in the Masjid, with no electricity. I was reading Quran under candle light and I just felt sleep. I just felt somebody touched my back and was waking me as soon as i woke up i felt somebody walking back as it was creating slight noise of foot steps on the floor, I found that the candle had almost starting burning the wooden base on which it was standing.
Whoever it was but He was kind enough to save me and the masjid. I just thanked Allah for helping me..
2nd One..
Second one happened to the neighbour of my best friend. The neighbours house and the house of my friend are close by and one can go inside the others house from interconnected doors.
While one day i had gone there and was sitting, my friend and his family hadnt slept for days as the Jin in the neighbours house was causing fire on things. Cupboards, beds, doors were on fire and the Jin was making it clear that he is not happy. All the neighbours were trying to save the neigbourhood from fire and they were struggling with keeping pace on extinguishing the fire caused by Jin. Jin even had pushed some men out of windows while they were trying to extinguish the fire. The Jin was accepting the orders of the many sheikhs who was trying to pacify him and asking him to leave the house.
Soon i too heard a cry of women and kids in the house and we rushed to the spot to find that the Jin had once again starting burning things in the house, wallah it was chilling.
Then finally they got a very good sheikh who controlled the Jin and then fire stopped. They however had to keep one full sheep ( Cooked) at a place for the Jin.
Let me stop now here....
