The benefits of the saying of Allah the Exalted: “So ask them: Which is more difficult in creation, or what We created? Indeed, We created them from clinging clay.”

He said, in this noble verse, what indicates that the Messenger of Allah (peace and blessings be upon him) is obligated to convey the message and to argue with them, due to His saying, and that is the case, for Allah commanded him to convey what was revealed to him from his Lord, and commanded him to debate his people.
and He informed that He will argue with them, due to His saying, Branching from this benefit is that the duty of the people of knowledge who have inherited knowledge is like his duty in this regard; it is obligatory for them to argue with the people of falsehood and confront them. Branching from that is the clarity that knowledge is a type of jihad in the path of Allah, because the seeker of knowledge argues with the enemies of the Shari'ah with the truth to repel their falsehood. Sometimes the intellectual invasion is more devastating than the armed invasion, as you see. The intellectual invasion enters every house by the choice of the householder without finding opposition or resistance, but the military invasion does not enter the house, nor even the country, except after bitter fighting and strong defense. So the enemies of the Muslims sometimes dominate them with armed invasion and fighting, and this can be guarded against. Sometimes they do so with intellectual invasion, which is more severe and painful than armed invasion because it strikes the Muslims in the depths of their homes, and they do not know about it. Perhaps they will exit Islam and Islam will be wiped from their hearts completely, and they will not be aware, because they lure the Muslims with desires.
And when the heart immerses itself in desires, it forgets what it was created for; it forgets the worship of Allah, and there is no attachment to Allah (Mighty and Majestic) in its heart. You find the person in his standing, sitting, going, and coming thinking only of these desires and striving only for these desires, as if he was not created for anything else. Likewise, they nurture in the souls of the weak the exaltation of these disbelievers, that they are more advanced, more civilized, and on a straighter path, and the like of that. The Muslim is thereby melted and dissolved in the fires of these people. This is undoubtedly present, and many Islamic countries have lost their morale and their identity has been destroyed because of this intellectual invasion.
If the Islamic countries were invaded militarily, they would be destroyed in their bodies, but the hearts of the people would be averse to them and hateful of them. But the problem is that people are invaded by their characteristics, morals, and beliefs while they are sitting in their homes, and the hearts have been opened to them. This is the problem, and this is the destruction. Therefore, the invasion with the weapon of knowledge derived from the Book of Allah and the Sunnah of His Messenger is equal to, if not more beneficial and more eloquent than, the military invasion. So I urge you, may Allah bless you, and I urge myself, that we prepare the means to combat our enemies who want to invade our homes with their evil ideas and their polluted morals, rather, with their deviant ideas and their polluted morals, so that we protect the Muslims from the evil of these people, because their weapon is more devastating and stronger than the weapon of iron and fire, as is apparent. Perhaps one of you who went to other countries knows more than I know, which led to deviation in creed and drifting after desires, until some Islamic countries became as if they were countries of disbelievers.
And they are now trying to invade these countries with everything they can, until we sometimes find in the newspapers the call for the disappearance of the morals and customs of Muslims being published. Sometimes they publish advertising for European and Frankish fashions, and with this phrase they open an exhibition for Western fashions or European fashions or European trends or the like of that. All this is in order to corrupt our morals. And if the morals are corrupted, the creed is corrupted, and if the creed is corrupted, the attachment of the Muslims to their Lord is removed, and at that time they become the weakest of nations. We ask Allah... safety. Good, we stop at this.
