Ahmad Sirhindi: Means

“Therefore, it is necessary that infidelity should be cursed in order to serve the faith (Islam). Cursing unbelief in the heart is the lesser way. The greater way is to curse it in the heart as well as with the body. In short, cursing means to nourish enmity towards enemies of the true faith, whether that enmity is harboured in the heart when there is fear of injury from them (infidels), or it is harboured in the heart as well as served with the body when there is no fear of injury from them.
In the opinion of this recluse, there is no greater way to obtain the blessings of Allah than to curse the enemies of the faith (be impatient with them). For Allah himself harbours enmity towards the infidels and infidelity…
Once I went to visit a sick man who was close to death. When I meditated on him, I saw that his heart was layered with darknesses. I intended to remove those darknesses. But he was not yet ready for it… When I meditated more deeply, I discovered that those darknesses had gathered due to his friendship with the infidels. They could not be dispersed easily. He had to suffer torments of hell before he could get purged of them…”

“Before that kafir [Guru Arjun Deva] was executed this recluse [meaning himself] had seen in a dream that the reigning king had smashed the skull of idolatry. Indeed, he was a great idolater, and the leader of the idolaters, and the chief of unbelievers. May Allah blast him! The Holy Prophet who is the ruler of religion as well as the world, has cursed the idolaters as follows in some of his prayers – “O Allah, demean their society, create divisions in their ranks, destroy their homes, and get at them like the mighty one.”
It is required by religion [Islam] that jihad should be waged against the unbelievers, and that they should be dealt with harshly… It is obligatory on Muslims to acquaint the king of Islam with the evil customs of false religions… Maybe the king has no knowledge of these evil customs… Some Ulama of Islam should come forward, and proclaim the evils present in their (unbelievers’) ways… It will be no excuse on the Day of Judgment that they did not proclaim the tenets of the Shariat because they were not called upon (to do so)…”

“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.”

“Every person cherishes some longing in his heart. The only longing which this recluse (meaning himself) cherishes is that the enemies of Allah and his Prophet should be roughed up. The accursed ones should be humiliated, and their false gods disgraced and defiled. I know that Allah likes and loves no other act more than this. That is why I have been encouraging you again and again to act in this way. Now that you have yourself arrived at that place, and have been appointed to defile and insult that dirty spot and its inhabitants, I feel grateful for this grace (from Allah). There are many who go to this place for pilgrimage. Allah in his kindness has not inflicted this punishment on us. After giving thanks to Allah, you should do your best to ruin that place and their false gods… whether the idols are carved or uncarved. Let us hope that you will not act slow. Physical weakness and severity of the cold weather, comes in my way. Otherwise, I would have presented myself, and helped you in doing the job. I would have liked to participate in the ceremony and mutilate the stones…”

Maktubat-i-Imam Rabbani translated into Urdu by Maulana Muhammad Sa’id Ahmad Naqshbandi, Deoband, 1988, Volume III pp.707. This letter was also written to Shaikh Farid alias Nawab Murtaza Khan who had reached Kangra in November 1620 to conquer the fort and desecrate its temples. Jahangir had followed the Nawab in order to celebrate the victory by sacrificing cows and building a mosque where none had existed before.

“Islam and infidelity (kufr) contradict one another. To establish the one means eradicating the other, the coming together of these contradictories being impossible. Therefore, Allah has commanded his Prophet to wage war (jihad) against the infidels, and be harsh with them. The glory is Islam consists in the humiliation and degradation of infidels and infidelity. He who honours the infidels, insults Islam. Honouring (the infidels) does not mean that they are accorded dignity, and made to sit in high places. It means allowing them to be in our company, to sit with them, and talk to them. They should be kept away like dogs. If there is some worldly purpose or work which depends upon them, and cannot be served without their help, they may be contacted while keeping in mind all the time that they are not worthy of respect. The best course according to Islam is that they should not be contacted even for worldly purposes. Allah has proclaimed in his Holy Word (Quran) that they are his and his Prophet’s enemies. And mixing with these enemies of Allah and his Prophet or showing affection for them, is one of the greatest crimes…
…The abolition of jizyah in Hindustan is a result of friendship which (Hindus) have acquired with the rulers of this land… What right have the rulers to stop exacting jizyah? Allah himself has commanded imposition of jizyah for their (infidels’) humiliation and degradation. What is required is their disgrace, and the prestige and power of Muslims. The slaughter of non-Muslims means gain for Islam… To consult them (the kafirs) and then act according to their advice means honouring the enemies (of Islam), which is strictly forbidden…
The prayer (=goodwill) of these enemies of Islam is false and fruitless. It should never be called for because it can only add to their numbers. If the infidels pray, they will surely seek the intercession of their idols, which is taking things too far… A wise man has said that unless you become a maniac (diwanah) you cannot attain Islam. The state of this mania means going beyond considerations of profit and loss. Whatever one gains in the service of Islam should suffice…”
