Dara Shikoh (from wikipedia):
Niccolao Manucci, the Venetian traveler who worked in the Mughal court, has written down the details of Dara Shikoh's death. According to him, upon Dara's capture, Aurangzeb ordered his men to have his head brought up to him and he inspected it thoroughly to ensure that it was Dara indeed. He then further mutilated the head with his sword three times. After which, he ordered the head to be put in a box and presented to his ailing father, Shah Jahan, with clear instructions to be delivered only when the old King sat for his dinner in his prison. The guards were also instructed to inform Shah Jahan that, “King Aurangzeb, your son, sends this plate to let him (Shah Jahan) see that he does not forget him”. Shah Jahan instantly became happy (not knowing what was in store in the box) and uttered, “ Blessed be God that my son still remembers me”. Upon opening the box, Shah Jahan became horrified and fell unconscious.
