"Although Sirhindi wrote a number of treatises on Sufi themes, he is best known for his letters ( maktubat ) 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."
