Dara Shikoh
Guru Har Rai provided medical care to Dara Shikoh, possibly when he had been poisoned by Mughal operatives. According to Mughal records, Guru Har Rai provided other forms of support to Dara Shikoh as he and his brother Aurangzeb battled for rights to succession. Ultimately, Aurangzeb won, arrested Dara Shikoh and executed him on charges of apostasy from Islam. In 1660, Aurangzeb summoned Guru Har Rai to appear before him to explain his relationship with Dara Shikoh.
