Amira Masood leaves Walford after finding out Syed Masood is having an affair with Christian Clarke, though she is carrying a baby, which he does not know about. When Amira returns to Walford over a year later, she meets Yusef Khan, who believes she has come to discuss getting divorced. However, Amira reveals that she wants Syed to meet his daughter. Yusef tries to persuade her she is doing the wrong thing and that Syed will want custody of Yasmin.
However, Amira goes to Syed and Christian's engagement party and tells Syed he has a daughter but she does not want Christian to have anything to do with Yasmin but Syed refuses to visit without Christian.
However, he later meets Amira and Yasmin in the park. Amira tries to manipulate Syed into spending more time with her and Yasmin. Amira lies, saying that Yasmin has swallowed her ring, leading to Yasmin going for an unnecessary trip to the hospital.
Yusef, trying to tear the Masood family apart, tells Christian that Syed may not be Yasmin's father so he and Christian get a paternity test done, taking a hair from each of them. However, Yusef, who is the local GP, swaps Syed's hair sample for one of his own.
The test results then show that Syed is not Yasmin's father, causing consternation for those involved, though Yusef's falsification is subsequently exposed. When Amira leaves Walford, she leaves Yasmin with Syed and Christian.
When Christian enters Yasmin into a "beautiful baby" competition, Syed becomes angry and refers to Yasmin as his daughter, not his and Christian's, leading to an argument between them. Amira returns a few months later as she wants Yasmin to live with her and her new fiancé in Birmingham. Syed eventually agrees but when Christian finds out, he tries to stop her.
Syed tells him that it is for the best and after agreeing to stay in touch, Amira and Yasmin leave after a tearful goodbye. However, Syed and Christian soon leave Walford to move nearer to Yasmin. In May 2014, Yasmin appears when Ian Beale visits Christian at his home in Birmingham, following the death of his daughter Lucy Beale. Christian is looking after Yasmin whilst Syed is at work and Ian is affected by seeing Yasmin, telling Christian the sort of things to expect with having a daughter, and when she grew up.
