Ok. I have another question, can the Qadr be changed? Qadr is desteny righ? so if I ask Allah " Oh Allah, if my desteny is such and such please change it, make me such and such" or " Oh Allah if you see that in my future I will become a kafir (may Allah protect me from this), please change my future" or "Allah if I am predestined to hell, please change my predestination, make me one of those from paradise" ?

is it allowed to make dua in this way?

and I've heard that if someone sins or if someone does good deeds it can change the Qadr, and also duas can change Qadr.. but there's something that doesn't convince me in this.. don't know what.. that's why I said that I am not so claver to understand everything.. may Allah forgive my ignorance! amin..
