Ulema Jealousy of the Sikhs:

Later, when Aurangzeb's forces chased Dara seeking his death before he could rally forces to retake the Mughal throne, Dara Shikoh came to the Punjab and sought the protection and help of Guru Har Rai. The Guru not wanting to defy his grandfather’s tenets would not allow the Sikhs to aid in an armed confrontation. But his tactical manoeuvres delayed the crossing of the river at Goindwal of Aurangzeb’s army, thus enabling Dara to escape. The Guru’s strong cavalry of 2,300 riders had removed all the boats which the Mughal army had needed to cross the river.

The Sikhs aid in Dara’s escape had already developed bitterness in Aurangzeb’s mind against the Sikhs. The humane practices of Guru Har Rai as opposed to the atrocities of the Mughals, had led to many Hindus whether Dalit or Brahmin to turn to Sikhism instead of accepting Islam. Guru Har Rai’s accomplishments were angering the Muslim clergy around Aurangzeb. They incited the Emperor claiming that lines in the Holy Granth Sahib disparaged the Holy Qur'an and Muslim doctrine. They asked him to summon the Guru to Delhi to explain these phrases.
