She was the daughter of Aurangzeb (Abul Muzaffar Muhiu ‘d-Din Muhammad Aurangzeb), the Moghal king who ruled India for a long period of 49 years from 1657 to 1707. When she was in Lahore (now in Pakistan), she fell in love with a young man, who was then occupying a top position in the overall administration of Aurangzeb. When Aurangzeb got a hint of such an affair, he ordered that she be brought back to Delhi, where she was provided a separate palace to live at a location presently known as Tees Hazaree. The man concerned too was deeply in love with Zaib-un-nissa, fully committed with a keen love for her. He left Lahore for Delhi to follow his love, and there he joined the palace staff of Zaib-un-nissa as a gardener in a disguised manner. This way, he was able to meet his love frequently on some pretext or the other.
When Aurangzeb came to know about it through his spies, he waited for an opportunity to brutally kill the man. One day, when Zaib was in her room with the man, Aurangzeb barged into the palace. Sensing this, Zaib asked the man to hide himself inside an empty big sized bronze pitcher lying nearby meant for keeping hot water to be used by Zaib for the purpose of a bath. By this time, Aurangzeb was there. He expressed his desire to himself take a bath there itself pretending as if he didn’t know that it was empty. Accordingly, the pitcher was placed on the heap of burning logs to ostensively heat the water up, and this heating process continued till such time the man got fully roasted and burnt to a tortuously torturous death. Aurangzeb had a hearty laugh on the success of his plan. Zeb was stunned, and looking like a stone, she fainted.
