أحمد بن زين الدين الأحسائي
According to Simon Digby, "modern hagiographical literature emphasizes Sirhindi's reiterated profession of strict Islamic orthodoxy, his exaltation of the shariah and exhortations towards its observance." On the other hand, Yohanan Friedmann questions how committed Sirhindi was to shariah by commenting: "it is noteworthy that while Shaykh Ahmad Sirhindi never wearies of describing the minutest details of Sufi experience, his exhortations to comply with the shariah remain general to an extreme." Friedmann also claims "Shaykh Ahmad Sirhindi was primarily a Sufi interested first and foremost in questions of mysticism.". Sirhindi wrote a letter to Mughal emperor Jehangir emphasizing that he is now correcting the wrong path taken by his father, emperor Akbar.
