- One day the old emperor Shah Jahan became ill. His son Aurangzeb, who always wanted to be the emperor, put his father in a jail. Jahanara Begum, the eldest child of Shah Jahan, did not leave her father and went to jail along with him. She said, “I shall share the suffering of my father. He needs me in his old age, and I shall never leave him.” Shah Jahan spent seven years in jail before dying. During that period, Princess Jahanara stayed there and took care of him. After the death of her father, she returned to her own palace and continued to live there till her death. Before her death, however, she gave away all she had to the needy and the poor. Upon her death, Aurangzeb gave her the posthumous title : Sahibat-uz-Zamani (mistress of age).
