A few specimens should suffice to show the quality of this man’s mind. In letter No. 163 he wrote: The honour of Islam lies in insulting kufr and kafirs. One who respects the kafirs dishonours the Muslims… The real purpose of levying jiziya on them is to humiliate them to such an extent that they may not be able to dress well and to live in grandeur. They should constantly remain terrified and trembling. It is intended to hold them under contempt and to uphold the honour and might of Islam.” In Letter No. 81 he said: Cow-sacrifice in India is the noblest of Islamic practices. The kafirs may probably agree to pay jiziya but they shall never concede to cow-sacrifice.” After Guru Arjun Deva had been tortured and done to death by Jahangir, he 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.”
Before that kafir [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.”
It is required by religion [Islam] that jihad should be waged against the unbelievers, and that they should be dealt with harshly… It is obligatory on Muslims to acquaint the king of Islam with the evil customs of false religions… Maybe the king has no knowledge of these evil customs… Some Ulama of Islam should come forward, and proclaim the evils present in their (unbelievers’) ways… It will be no excuse on the Day of Judgment that they did not proclaim the tenets of the Shariat because they were not called upon (to do so)…
It is said that the Shariat prospers under the shadow of the sword (al-Shara‘ tahat al-saif). And the glory of the holy Shariat depends on the kings of Islam…
