but I liked how sobia says it in open.armaan ke samne she says that ke hamza loves ujaala.but sabia begun cannot be counted out yet.I think she knows a bit about hamza/ujaala angle as ujaala tried to warn her in past.In her selfishness she will help ujaala stay in good books of Armaan.
I feel ujaala rooth jaegi Armaan se ....she will think of it as ultimate sin by offering his own wife to his friend.
Sami I dont think armaan will want Hamza marry ujala . At the end of the Hamza is a play boy for him. He knows hsmza has multiple affairs
