Final answer:
The Persian tutor who helped Guru Gobind Singh Ji was Bhai Nand Lal Ji. Sikhism was founded by Guru Nanak Dev Ji, and it was a Sikh, Guru Tegh Bahadur, who was executed by Aurangzeb.
Step-by-step explanation:
The Persian tutor of Guru Gobind Singh Ji who helped him when he was called to identify 'Uch-da-Peer' was Bhai Nand Lal Ji.
Guru Tegh Bahadur, the ninth Sikh Guru, was executed by Aurangzeb. He was a leader of the Sikh religion. Furthermore, Guru Nanak Dev Ji was the founder of Sikhism and the first of the eleven Sikh Gurus.
Sikhism is a distinctive faith established in the Indian subcontinent by its enlightening founder Guru Nanak Dev Ji and further shaped by nine successive Gurus.
It is important to note that neither Krishna nor Buddha can be called the 'founder' of Hinduism as it is a complex faith with roots stretching far into antiquity, beyond the advent of a single founder.
