الحمد لله رب العالمين، وصلى الله وسلم على نبينا محمد وعلى آله وأصحابه أجمعين، أما بعد
Shaikh Saalih bin Fawzaan Al-Fawzaan (hafidhahullaah) said:
“Then there is a da’wah which poisons the mindset of the youth against their fathers and their societies – as well as against their rulers. It is likewise a da’wah to corruption which they call Jihaad, it models itself with making permissible the blood of the Muslims as well as those under agreed treaties and the one whose safety is guaranteed, and bringing ruin to the building structures and the residences and the properties (possessions) by way of devastating explosives and horrifying terrorism.
So upon you O Muslims is to be cautious of these hidden gatherings – suspicious meetings; and journeys that are unknown. Safeguard your children from the callers to tribulation, those that sneak in amongst them and so they meet with them and then inculcate them with those very ideologies. Then they cause your sons to become isolated from you – and so you lose them until it is announced concerning them – after they have been captured or after they are killed – after their having engaged in devastation and aggression against the people – or even after their being consigned to the prisons.
So be aware of the callers to tribulation about whom the Prophet (sallallaahu ‘alaihi wa sallam) said:
((They will be from our own people and will speak in our language.))
Yes; they indeed speak in the name of knowledge and disguise themselves in the garment of religiousness – out of deceit and slyness; out of extremism and going beyond bounds. They declare others to be ignorant or they attribute hypocritical lip service unto them, as well as proceeding in order to attain rank/position and worldly profits. Or that they characterize them with cowardice and lingering behind from Jihaad – and other than that from the false accusations.
How then can you be negligent O Muslims with regard to these people and you are careless in their affair and you leave your children in their hands? They direct them to their destruction as well as your own destruction and the destruction of the society.”
Concerning the youth; the Shaikh said elsewhere:
“The youth should avoid the innovators and the people of destructive methodologies and misguided ideologies; they should keep away from them and from their books and instead adhere to the people of knowledge and insight and the people of sound beliefs, they should take knowledge from them and sit and ask them. As for the people of innovation and destructive ideologies; then it is obligatory upon the youth to keep away from them because they are harmful to them and they plant corrupt beliefs amongst them as well as innovations and nonsensical drivel.
The teacher has an effect upon the learner, thus a teacher who is astray will deviate along with the youth and the students, whilst the upright teacher – then at his hand the students and the youth will remain upright.”
