After giving birth to her fifth child, Muhammad Akbar, Dilras Banu Begum possibly suffered from puerperal fever, due to complications caused by the delivery and died a month after the birth of her son on 8 October 1657. Upon her death, Aurangzeb's pain was extreme and their eldest son, Azam Shah, was so grieved that he had a nervous breakdown. It became Dilras' eldest daughter, Princess Zeb-un-Nissa's responsibility to take charge of her newborn brother. Zeb-un-Nissa doted on her brother a lot, and at the same time, Aurangzeb greatly indulged his motherless son and the prince soon became his best-loved son.
