Shah Jahan had 5000 women in his harem and even had incestuous relations with his own biological daughters.

“Several European chroniclers have suggest that Shah Jahan had an incestuous relationship with his daughter Jahanara Begum. The European traveller Francois Bernier wrote, "Begum Sahib, the elder daughter of Shah Jahan was very beautiful... Rumour has it that his attachment reached a point which it is difficult to believe, the justification of which he rested on the decision of the Mullas, or doctors of their law. According to them it would have been unjust to deny the king the privilege of gathering fruit from the tree he himself had planted." Joannes de Laet was the first European to write about this rumour. Peter Mundy and Jean Baptiste Tavernier have also written about the same allegations.”

A reference to these allegations can be found in François Bernier, Travels in the Mogul Empire, A.D. 1656-1668, translated by A. Constable and edited by V. A. Smith (1914).
