"Khoon ka rang nahi badla jaata!"
In his own mind, Asad's worst nightmare has come true - he's become his father. I'm pretty sure everyone's caught on with that. But what I think is the reason behind all this happening to Asad is the fact that he's hated his father all these years without ever trying to find out his father's side of the story.
So now, he's been put in the very father's shoes he always refused to hear out. And when it all boils over and Asad learns that he was all part of a saazish (as I'm sure he one day will), he will finally be able to see things from his father's point of view. Asad will be more willing believe his father when Rashid tries to explain to him that he was caught in a saazish as well, just as he was.
And that's where acceptance will finally come into play, which is supposed to be the essence of Qubool Hai. Asad accepting his father. After all, you can only better understand what another person has gone through if you've gone through it yourself.
