Guru Arjan quotes

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 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 death was by execution, the result of torture, or drowning in the Ravi River remains unresolved. For Sikhs, Arjan is the first martyr Guru. (Guru Arjan)
These days the accursed infidel of Gobindwal was very fortunately killed. It is a cause of great defeat for the reprobate Hindus. With whatever intention and purpose they are killed – the humiliation of infidels is for Muslims, life itself. Before this Kafir (Infidel) was killed, I had seen in a dream that the Emperor of the day had destroyed the crown of the head of Shirk or infidelity. It is true that this infidel [Guru Arjun] was the chief of the infidels and a leader of the Kafirs. The object of levying Jizya (tax on non-Muslims) on them is to humiliate and insult the Kafirs, and Jihad against them and hostility towards them are the necessities of the Mohammedan faith.

Guru Arjan
Before that kãfir [Guru Arjun Deva] was executed this recluse [meaning himself] had seen in a dream that the reigning king had smashed the skull of idolatry. Indeed, he was a great idolater, and the leader of the idolaters, and the chief of unbelievers. May Allah blast him! The Holy Prophet who is the ruler of religion as well as the world, has cursed the idolaters as follows in some of his prayers – "O Allah, demean their society, create divisions in their ranks, destroy their homes, and get at them like the mighty one.”.

Guru Arjan
After Guru Arjun Deva had been tortured and done to death by Jahangir, he [Ahmad Sirhindi] wrote in letter No. 193 that "the execution of the accursed kafir of Gobindwal is an important achievement and is the cause of the great defeat of the Hindus.”. View quote
