Analysis of information sources in references of the Wikipedia article "Guru Arjan" in English language version.
Quote: Jahangir, Akbar's son and successor, had ordered the execution. We know from Jahangir's own handwriting that he was jealous of Guru Arjan Dev's popularity and that a gesture from the Guru towards Khusrau, a son rebelling against Jahangir, had outraged him.
"The Mughal rulers of the Punjab were evidently concerned with the growth of the Panth, and in 1605 the Emperor Jahangir made an entry in his memoirs, the Tuzuk-i-Jahāṅgīrī, concerning Guru Arjan's support for his rebellious son Khusrau Mirza. Too many people, he wrote, were being persuaded by his teachings, and if the Guru would not become a Muslim, the Panth had to be extinguished. Jahangir believed that Guru Arjan was a Hindu who pretended to be a saint, and that he had been thinking of forcing Guru Arjan to convert to Islam or that his false trade should be eliminated, for a long time. Mughal authorities seem plainly to have been responsible for Arjan's death in custody in Lahore, and this may be accepted as an established fact. Whether the death was by execution, the result of torture, or drowning in the Ravi River remains unresolved. For Sikhs, Arjan is the first martyr Guru.
The author of the Dabistan refers to the blessings of Guru Arjan for the rebel Prince Khusrau. A heavy fine was imposed on Guru Arjan, which he was unable to pay. He was bound and kept on the hot sands of Lahore. He died due to the heat of the summer and the tortures inflicted by the officials responsible for collecting the fine.
