Bibi Ka Makbara and Safdarjang Tomb were not built during the Delhi Sultanate period. Bibi Ka Makbara, sometimes referred to as the "Taj of the Deccan," was constructed by Aurangzeb's son, Azam Shah in the memory of his mother Dilras Banu Begum, in the 17th century, long after the end of the Delhi Sultanate. Safdarjang Tomb, similarly, is a later Mughal construction, specifically built by the vizier Safdarjung in the mid-18th century, marking the decline of Mughal authority in Delhi.
