Politically speaking, the general perception of Jahangir has been that, like his father before him, he was a leader said to be "tolerant" of non-Muslims and their respective religious practices:
"Like Akbar, Jahangir managed diplomatic relations on the Indian subcontinent adroitly, was tolerant of non-Muslims, and was a great patron of the arts. He encouraged Persian culture in Mughal India."

This attitude was similarly witnessed first hand by a disinterested historical source and a contemporary of Jahangir: Edward Terry. On his voyage to East India between 1616-1619, the English chaplain - who referred to Jahangir as The Mogul - said of his administration:
In that empire all religions are tolerated, which makes the tyrannical government there more easy to be endured. The Mogul would speak well of all of them; saying, that a man might be happy and safe in the profession of any religion; and therefore would say that the Muslim religion was good, the Christian religion good, and the rest good; therefore the ministers of any religion find regard and esteem amongst the people. I shall speak something of this, from my own particular usage there, then very young, while I lived in those parts...

Terry then recounts a story that he witnessed of a man who was summoned in the presence of Jahangir after converting to Christianity. The King attempted to convince him "to renounce that his new profession" firstly by way of threats, and then with promises of riches. When Jahangir "perceived that his resolution indeed was to be a Christian... he [Jahangir] bid him to continue, and with a reward discharged him".
Concerning Terry, Prof. Alison Games of Georgetown University observes that "he [Terry] applauded the freedom of religion that all enjoyed".
First of all Jahangir was not at all one of the most fanatic mughal ruler but on the other hand he too was not at all very comfortable with muslims converting to other religions.
Just here read what he wrote in his diary
This is what Emperor Jahangir wrote in his diary called the Tuzk-e-Jahangiri, which translates to "Memoirs of Jahangir"
“ In Goindwal, which is on the river Biyãh (Beas), there was a Hindu named Arjan, in the garments of sainthood and sanctity, so much so that he had captured many of the simple-hearted of the Hindus, and even of the ignorant and foolish followers of Islam, by his ways and manners, and they had loudly sounded the drum of his holiness. They called him Guru, and from all sides stupid people crowded to worship and manifest complete faith in him. For three or four generations (of spiritual successors) they had kept this shop warm. Many times it occurred to me to put a stop to this vain affair or to bring him into the assembly of the people of Islam.
At last when Khusrau passed along this road this insignificant fellow proposed to wait upon him. Khusrau happened to halt at the place where he was, and he came out and did homage to him. He behaved to Khusrau in certain special ways, and made on his forehead a finger-mark in saffron, which the Indians (Hinduwän) call qashqa, (Tilak) and is considered propitious. When this came to my ears and I clearly understood his folly, I ordered them to produce him and handed over his houses, dwelling-places, and children to Murtaza Khan, and having confiscated his property commanded that he should be put to death." „
