I have a younger brother who used to abuse me all the time before. It is due to some black magic because my brother was initially a very dear friend of mine. Then he stayed out of the house for two years with a relative of ours. When he came back he was absolutely changed. We have listened to his abuse for 7-8 years. But now we are calm rather the day on which I performed this deed, he stopped abusing. I only performed the deed once and the state of the certainty of belief I had that time is only known to me, I just read it and it happened. The deed is as follows: In the midnight the forehead has to be prostrated on the ground and while prostrating Al-Muzzil-o has to be recited for 55 times. And while prostrating three times the following has to be recited:  الٰہِیْ اَیْمَنِّیْ مِنْ فُلَانَ یَامَذِلُّ Translation: O Lord! Save me from the humiliation of so and so person.
