Did Anjana & Waseem conspire to get rid of Pooja &Yash ?

There are a few who believe that it is Anjana & Waseem who together conspired to murderPooja & Yash. Is there any evidence in earlier episodes that point to this ? Anjana has been accused by Sakshi for taking Pooja's life but what about Waseem? Do you think he is involved in some way? Is that why he did everything possible to stop Zoya marrying Aditya when he saw the two so close to each other? Did he do this because he feared Anjana may do to Zoya what she did to Pooja? Is this the reason he hates the Hooda's
