I think Parvez did know that his second child with Kausar was a girl and he wasnt willing to raise another girl, and so he left the baby. Sultana and Fareed then adopted the babyIn one episode Sultana was shown in OT, doing surgery ( most probably Kawsar's while she was giving birth to Amal)and confessed Fareed that she knows Kawsar is Amal's mother. What does that mean? She stole Amal from OT or ifound her in the parking lot? Parvez mentioned about a dead son( might be Amal. He knows he had a dead son instead of Amal) in one episode and cursed Kawsar. Sultana also told Fareed that if Parvez knew Amal is his daughter he would do the same as he is doing to Seher. Means Parvez never knew Amal's existence. I missed 1/2 initial episodes.So not sure.
It was the initial promo of this serial where Kawsar is with Seher one side and on other side/other screen Maheed( more like anti).

Sp that lady works as negative character.
