Help plz !

Hi! I want to know the name of this serial, I just remember the storyline but cant remember the name, dates some time back.

The two stories of two sisters - later we come to know the other one is a cousin who has been adopted, her sister cannot conceive, then they marry the other girl to the same husband, so that saut is her own. However, later on the first wife starts to get jeolous of the growing closeness between them. In the meantime the guy who the other girl was in love, his name was Kabir gets married to some friend or something. The other sister gets pregnant, and the first wife asks her to say it is not their husbands, and she wants a talak, she asks so in front of a lot of people, the husband agrees, they all think it is Kabir's but he says its not, they ask her who's she doesnt reply, she lives isolated from the family. and that about it all i know...
