„The Shariat prevails under the shadow of the sword (al Shara‘ tahat al-saif) - according to this (saying), the Shariat can triumph only with the help of mighty kings and their good administration. But for some time past this saying has been languishing, which means inevitably that Islam has become weak. The unbelievers (Hindus) of Hindustan are demolishing mosques, and erecting their own places of worship on the same sites. There was a mosque in the tank of Kurukhet (Kurukshetra) at Thanesar, as also the tomb of some (Muslim) saint. These have been demolished, and a huge gurudwara has been constructed on the same sites. Besides, the kafirs are holding many celebrations of kufr…
It is a thousand pities that the reigning king is a Mussalman, and we recluses find ourselves helpless. There was a time when Islam stood glorified due to the might and prestige of its kings, and the Ulama and the Sufis were honoured and held in high regard. It was with their help that the kings made the Shariat prevail. I have heard that one day Amir Taimur was passing through the bazar at Bukhara when, by chance, the inmates of Khwaja Naqshbandi’s khanqah were beating the dust out of the mats used in that place. Because Islam was intact in Amir Taimur, he stopped at that spot and regarded the dust of the khanqah as musk and sandal. He met a good end.“
