I read so many posts discussing on why zoya is shown as a Muslim character. I had replied to a post & then thought of making it a separate post. So my thoughts on the topic:
I think it was quiet conscious decision of making zoya a muslim girl. The show is breaking so many stereotypes quietly. Having both leads from different religions makes their relationship all the more special. Although both of them are not deeply religious but they certainly r well versed with rituals & customs. So if zoya despite being prohibited by her religion to marry a person outside her religion marries a hindu not once but twice shows her rebellious streak , inner strength & determination to go beyond the society norms & truly follow her heart. We have seen her being so stubborn be it in her belief on yash, paak rishta & latest arshad track. The girl is stubborn to d core & only does what her heart wishes. Has she been a hindu, her decision to marry either yash or Aditya wouldn't have been received so much discussion. But here she is defying the norms of society not once but twice. So in a way cvs r challenging the society norms by making her breaking norms & not the Aditya.
They could have shown ML as Muslim & zoya hindu. But then a man breaking stereotype is not new but a girl doing that is big.
If they haven't shown families having any objections on their alliance it's b'coz generally the affluent class doesn't really conform to the rigid society norms. There have been many instances in real world where the industrialists, movie stars, business people do opt for inter religion marriages. I think that's why they have purposely showed zoya's family as an affluent family as then families approving the alliance would be much more believable as they would like to pride themselves on secular & liberal mindset. That liberal upbringing has given zoya the strength to look beyond the society norms & follow her heart. I remember there was a scene after she gets award post leap when while returning back from the award ceremony she stopped near church to pray & Waseem doesn't object at all signifying that he doesn't have any rigid ideas about religion & is liberal in this aspect.
