Confused after Razia self confession

During the self confession scene in the factory, Razia said that after the incident Rashid became the puppet in her hands and did whatever she asked him to do. She asked him to do Nikkah with Shireen and he did that. This is where my confusion starts... Aayan was already few years old at the time of Najma's first birthday and he was living with Asad and his family n than Rashid went and took him from there by force(as shown in the flashback) and went to live with Shireen due to Razia's back bailing but does it mean that Nikkah of Rashid and Shireen was done after the incident of gudhya factoryas claimed by Razia in today's episode? If that's the case is Ayaan an illegitimate child of Rashid and Shireen? Please guys somebody help me in understanding the past events. They are confusing me more and more with the revelation of the past or maybe CV's have lost the dots somewhere during the narration of the story. Please help!
