After Aurangzeb’s death when Muslim power started to disintegrate, the Sufi scholar Shah Waliullah (1703-1763) wrote to the Afghan King Ahmad Shah Ab… - Shah Waliullah Dehlawi

We are strangers. Our forefathers came to live in India from abroad. For us, Arab descent and the Arabic language are cause of pride, because these two bring us nearer to the Lord of First and the Last, the noblest of the Prophets and Apostles.

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 assured… You should forge unity with Musa Khan and other Muslim groups, and put to use this friendship and unity for facing the enemies. I hope for sure that on account of this unity among Muslims and their nobility, victory will be achieved.
The reason for the rise of enemies and the fall of Muslims is nothing except that, led by their lower nature, Muslims have shared their (Muslims’) concerns with Hindus. It is obvious that Hindus will not tolerate the suppression of non-Muslims. Being farsighted and practising patience are praiseworthy things, but not to the extent that non-Muslims take possession of Muslim cities, and go on occupying one (such) city every day… This is no time for farsightedness and patience. This is the time for putting trust in Allah, for manifesting the might of the sword, and for arousing the Muslim sense of honour. If you will do that, it is possible that winds of favour will start blowing. Whatever this recluse knows is this that war with the Jats is a magic spell which appears fearful at first but which, if you depend fully on the power of Allah and draw His attention towards this (war), will turn out to be no more than a mere show. Let me hope that you will keep me informed of developments and the faring of your arms…

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
