Haider Akhtar is a wealthy businessman who is married to Dua, a kind woman. Their lives take a turn when they meet an outspoken woman, Ghazal, who befriends Dua but is at loggerheads with Haider. Haider and Dua offer shelter to Ghazal in their own house after her house gets destroyed by an earthquake. Haider befriends Ghazal too. Ghazal falls in love with Haider but tries to forget him for Dua's sake. Haider's stepmother, Gulnaaz, instigates Ghazal and reveals to her how Haider's mother, Hina, had caused Ghazal's mother's death years ago. Before dying of cancer, Ghazal's father had proposed Haider and Ghazal's marriage but Hina had declined as Dua was already engaged to Haider at that time. Ghazal turns vengeful and pretends to have forgiven Hina but vows revenge.
When Dua discovers Ghazal's grudge against Hina, she attempts to evict her from the house. Ghazal lies to Gulnaaz's son, Ruhaan, who was in love with her, that she loves him too and Hina fixes their alliance. Gulnaaz turns against Ghazal. Ghazal creates circumstances and manipulates Ruhaan into believing that she and Haider are having an affair. Thus, Ruhaan runs away on the wedding day with Dua's help. Ghazal gets Ruhaan abducted by her cousin, Ejaz. Dua is blamed for Ruhaan's escape. Ghazal reveals to Haider that Hina was responsible for her parents' death and pretends to commit suicide if he doesn't marry her.
Feeling guilty for Hina and Ruhaan's actions, Haider ends up marrying Ghazal. Everyone in the house refuses to accept Ghazal, except Hina who turns against Dua. Dua, motivated by her mother Hamida, turns bold and rebellious, refusing to perform her duties as a daughter-in-law and a wife. Ruhaan is rescued and brought back home, but he believes Dua and Haider to be his enemies. Later, Ruhaan learns about Ghazal's schemes and reconciles with Dua. Ghazal is finally exposed but she pushes Hina off the balcony, causing her to loose her memory. Ghazal uses Haider's sperm samples and gets pregnant via IVF. Once Hina recovers her memories, the Akhtar family lodge a police complaint against Ghazal. Still on the run from the police, Ghazal goes into hiding, thus concealing her pregnancy from everyone. Dua is also revealed to be pregnant.
Six months later, Kaynaat, Haider's sister, gives birth to her son, Subhaan. Dua's baby shower ceremony is interrupted by Ghazal who reveals her pregnancy and demands her rights. Dua allows Ghazal to stay in a warehouse under surveillance, near the Akhtar mansion. Kaynaat's hatred grows against Ghazal and her unborn child as she considers it as a threat to her family. Kaynaat is ousted from the house by Dua after she abducts Ghazal. With Dua’s help, Ghazal delivers a baby girl, Ibaadat.
Shortly, thereafter Dua too delivers a baby girl, Mannat. Realizing that she won't be able to live happily with Haider ever, Ghazal jumps down from the cliff, pulling Haider along with her, resulting in both of their deaths. Kaynaat blames Dua for Haider's death as she had previously ignored her warning to oust Ghazal from the house. Soon, Kaynaat is forced to shift to London with her family after she tried to kill Ibaadat again and vowed revenge on Dua.

Mannat decides to snatch Subhaan from Ibaadat, after Kaynaat reveals to her the story of Dua-Haider-Ghazal and that Ibaadat is Ghazal's daughter.
