In The Name of Allaah, The Most Merciful, The Bestower of Mercy.
Allaah [The Most High] said: [ وَكَذَٲلِكَ جَعَلۡنَا فِى كُلِّ قَرۡيَةٍ أَڪَـٰبِرَ مُجۡرِمِيهَا لِيَمۡڪُرُواْ فِيهَاۖ وَمَا يَمۡڪُرُونَ إِلَّا بِأَنفُسِہِمۡ وَمَا يَشۡعُرُونَ – And thus We have set up in every town the greatest of its criminals to plot therein. But they plot not except against their ownselves, and they perceive (it) not]. [Soorah Al-An’aam: Ayah 123]
[وَكَذَٲلِكَ جَعَلۡنَا فِى كُلِّ قَرۡيَةٍ أَڪَـٰبِرَ مُجۡرِمِيهَا – And thus We have set up in every town the greatest of its criminals] – Meaning: Those figureheads whose crimes were great and whose transgressions were severe. [لِيَمۡڪُرُواْ فِيهَاۖ -to plot therein]- Meaning: Through deception, calling to the path of shaytaan and waging war – through speech and deeds- against the Messengers and their followers. However, their plots and machinations only backfired on them. That is because they plotted and Allah too was planning, and Allah is the Best of the planners.
Likewise Allaah set up great ones amongst the leaders of guidance and the most virtuous of them, who opposed those criminals, refuted their statements and strove against them in the path of Allaah. They followed the paths leading to the path (of Allaah) and Allaah aided them. Allaah gave them an acute discernment and kept them steadfast. So the days of victory and defeat alternated between them and their enemies, until the affair came to its final end-victory and triumph (for the believers) and the good final end is for the Muttaqoon (i.e. the pious and righteous persons who fear Allah much (abstain from all kinds of sins and evil deeds which He has forbidden) and love Allah much (perform all kinds of good deeds which He has ordained)].

Analysing The Plots of The Disbelievers – A Fard Kifaayah
Shaikh Rabee Bin Haadee Al-Madkhalee (may Allaah preserve him) says:
So it is not permissible for the Ulamaa to remain heedless of their plans (i.e. the enemies of Islaam), their actions, their publications, their missionary activities and their various calls (to the Muslims). And also the various poisons they are infusing – which are in opposition to the Quraan and the Messenger (sallallaahu alayhi wasallam) and his Sunnah. And nor of what plans they have for (the destruction of) the beliefs and methodologies of Islaam. It is not permissible either, to remain heedless of their concentrated efforts to Christianize or secularize the Muslim youth. And along with that, the Muslim youth and the students are not able to oppose this plan and strategy. Rather it is necessary that the distinguished Ulamaa – those who are experienced and shrewd – it is for such people, in all the places to undertake this duty. So it is obligatory for some of the intelligent and ingenious people from the field of Aqeedah to be mobilised for opposing these plans. And likewise it is a must that the intelligent and distinguished from amongst the specialists in the Sunnah – that they be mobilised for the refutation of these and similarly the eminent and distinguished from amongst those in the fields of Orientalism for the refutation of the plans of the Orientalists.” (Ahl ul-Hadeeth, p.102)
He also says: “I myself believe that it is a benefit – rather it is of necessity – that we know what the enemies are planning for us, and that it is necessary for us to prepare (ourselves in strength) to destroy their plans. However, I do not exaggerate in this matter, rather my view is the view of our Ulamaa and they have all agreed upon this – that amongst the obligatory matters there are some that are Fard Ain and others that are Fard Kifaayah – and even if knowing the state of the enemies is harmful – it is still necessary for us to know it – but it is treated as Fard Kifaayah. When some attend to it, then the harm is removed from the rest” up until he said: “So I consider that there is no criticism for the Ulamaa and the students of knowledge who take great concern for preserving the Sharee’ah of Allaah – in terms of the Book, the Sunnah and its understanding – for this is one of the duties of the Kifaayah actions. And I believe that these people are more superior, noble, truthful and of more benefit to Islaam than those who are weak in their knowledge of the religion of Allaah or those who have no share in acquainting themselves with it.” [An excerpt from an article at www.salafipublications.com titled: The Salafis and Looking into the Affairs of the Ummah]
