Today's episode hinted at Shahbaz's conversation with Ruksar in the hospital.
Ruksar told Zeenat that Shabaz said Zara will marry Kabir but Ruksar will marry Kazi Kabir. I think Shahbaz made a deal with Ruksar that once Kabir becomes head priest, he will make Kabir divorce Zara and marry Ruksar instead.
I think that is where Triple Talaq will come in. Zara will be dead set against it and will fight for her right.
I just hope Kabir doesn't get two wives. I know that Islam culture allows it but hoping Zara won't let that happen.
