Superstitions

I have a problem. My brother in-law has some business problem. He went to see a person and it seems that now his problem is solved, am seeing that his business is flourishing. I don’t know what they did. But till that day, I can notice that his “bad luck” is following my husband and me. I am a religious person, I perform my salaat daily, I read Quran and other duas on a regular basis. My brothers in law, his wife are not at all religious. I can see that they are getting the reward for all the prayer that I am a doing. Moreover, all the projects that me and my husband are planning to do failed and we face lot of difficulties in doing something.
