Your honoured letter regarding suppression of the Jats has arrived. Allah is merciful, and it is hoped that he will crush the enemy. You should rest … - Shah Waliullah Dehlawi

Shah Wali Allah had been a late addition to his family. His father, Shah 'Abd al-Rahim, had long been one of the most respected in the Mughal real, and his talents and austere piety had won him and then cost him royal favor decades before his most famous son was born. When Shah Wali Allah was five, his father placed him in the school he supervised, and by seven the boy had memorized the Qur'an. He mastered Arabic and Persian letters soon thereafter and was married at fourteen. A childhood spent studying at his father's feet meant that by sixteen he had completed the standard curriculum of law, theology and logic along with arithmetic and geometry. A year later, Shah Wali Allah would recall poignantly, his father and greatest teacher 'Voyaged onward to the above of God's mercy.' The young student's ambition to seek ilm remained strong, and by nineteen he had exhausted the Knowledge of Dehli's scholars. So Shah Wali Allah voyaged across the Indian Ocean to perform his hajj pilgrimage and pursue his studies in the holy cities of Mecca and Medina. In the Prophet's mosque in Medina, at the feet of scholars from across the Muslim world, he studied a book to which he became exceedingly attached and which he viewed as the foundation for understanding the Prophet's Sunna. It was the Muwatta, the 'Well Trodden Path,' of the eight-century scholar of Medina, .

In this age there exists no king, apart from His Majesty [Ahmad Shah], who is a master of means and power, potent for the smashing of the unbelievers’ army, far-sighted and battle-tested. Consequently a prime obligation upon His Majesty is to wage an Indian campaign, break the sway of the unbelieving Marathas and Jats, and rescue the weaknesses of the Muslims who are captive in the land of the unbelievers. If the power of unbelief should remain at the same level (God forbid!), the Muslims will forget Islam; before much time passes, they will become a people who will not know Islam from unbelief. This too is a mighty trial: the power of preventing that is attainable for His Majesty alone, by the favour of the beneficent God . . . In the name of Almighty God we ask that he [Ahmad Shah] expend effort avidly for a holy war against the unbelievers of this territory, so that in the presence of Almighty God a fine reward may be inscribed in His Majesty’s book of deeds, so his name may be recorded in the register of holy warriors . . . so in the world innumerable foes may fall at the hand of the heroes [ghazi]of Islam, so Muslims may obtain rescue from the hand of the unbelievers. The victory of Islam is the destiny of the entire community; so, wherever there is a Musalman, [the Muslim warrior-kings] will love him on a part with actual sons and brothers; and wherever there is a warlike unbeliever, they will be like raging lions

God has charged His servants with what He has commanded and forbidden [and in this] He is comparable to a man whose slaves have become ill and bids a man of his household make them drink medicine—even if he compels them to drink it or forces it into their mouths—this is just; however, mercy ( rahma ) demands that he explain to them the benefi ts of the medicine so that they will desire to drink it, and mix honey with [the medicine] to assist in rendering the desire natural and sensible.
