"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."

“Kufr and Islam are opposed to each other. The progress of one is possible only at the expense of the other and co-existence between these two contradictory faiths is unthinkable.”

“Whenever a Jew is killed it is to the benefit of Islam.”

“Like many fundamentalists, Sirhindi has no tolerance for philosophers, since he believed that “the human intellect is incapable of understanding properly the nature of God without prophetic assistance.” But this rejection of the philosophers also “leads him to an equally indignant rejection of their natural sciences. Their geometry, astronomy, logic, and mathematics are useless as far as the hereafter is concerned and fall therefore within the category of ‘inconsequential things’ .”

“Although Sirhindi wrote a number of treatises on Sufi themes, he is best known for his letters to various Sufi shaykhs and Mughal dignitaries, which have been regarded as a turning point in the development of Indo-Muslim religious thought. Sirhindi’s insistence on strict adherence to the sharia was at least partially responsible for inspiring the Mughal emperor, Awrangzib, to carry out orthodox reforms that reversed the heretical developments of his prede- cessor, Akbar’s rule. ... Sirhindi also wrote a number of letters concern- ing the martial jihad and relations with non-Muslims under Muslim rule. In these letters, Sirhindi consistently advocates a harsh and uncompromis- ing stance toward the Hindus under Mughal rule.”

“As Ayesha Jalal points out, he was “a firm believer in the need to use state power to enforce Islam”.”

“It is therefore enjoined upon every Muslim to wage a regular crusade against all innovations.”
