why people dont understand Islam being a Muslim. Istakhara is not a signal or something like you have described why are we Muslims making Islam like the other religion. Istakhara is a two rakat prayer in which a person prays and says a dua that what ever the person is going to start may Allah help the person to show him or her the right direction . its not that you will get some signal or what. when you are involved in a relation or going to involve in any work it is according to Allah decision to step in it so how can we say that we will get red blue green black signals...its not like this...
