No matter where you go in the world, whether you are young or old, a man or a woman, you'll notice immediately that there exists a universal language in which everyone is fluent. Perhaps these people have never met one another; perhaps they live kilometers away from one another. They may come from different cultures, hold different beliefs, and speak different languages. But despite all this, they all share a common language that they know very well and use when the need arises—namely, the "silent language of evil."
This insidious language allows its speakers to do unseemly things they would never do openly, utter ugly things that they would not say directly and speak to one another in secret ways that no outsider would understand. Some hesitate to express openly the evil that lies within them because if they did so, they could provoke adverse reactions in those around them—which would not be to their benefit. But when they act in secret, they believe the subtle and intricate methods they use eliminate their risk of being found out. Indeed, those who speak in this silent language make themselves clearly understood. But because of the cunning it employs, no echo is left behind and there can be no proof.
An important question comes to mind: How did so many all around the world learn this language, with its multitude of rules? Certainly, someone must be teaching them the silent language of evil and urging them to use it in secret. The leader of evil, the one who's engaged in a merciless struggle against human beings, is satan.
Satan swore to Allah that he would teach people this language to draw them secretly into evil. With the aid of this language, he leads them to do things in secret that they would never dare to do openly. He tempts them to say things in secret that they could not utter openly. He leads people to secretly live the evil inside them instead of stamping it out. But in the Qur'an, Allah says that He has forbidden human beings to commit evil: "... you do not approach indecency – outward or inward..." (Surat al-An'am: 151)
Some who fall into this trap of satan's may avoid committing evil openly. But otherwise, they adopt satan's morality, speak his language and lead the sort of lives he wants them to lead. They seek to attain their goals and desires by applying this secret language's rules. They believe they can use the methods of this dark language to attain a good life and enjoy happiness, success and superiority. However, this stratagem of satan's cannot bring people happiness or contentment, but can only lead them into damage and destruction.
Allah warns us in the Qur'an against this danger:
O Humanity! Eat what is good and lawful on the earth. And do not follow in the footsteps of satan. He truly is an outright enemy to you. He [satan] only commands you to do evil and indecent acts and to say about Allah what you do not know. (Surat al-Baqara: 168-169)
But because some do not accept the Qur'an as their guide, they have been falling into satan's traps for centuries. Even though they have been led into misery, they cannot give up living in this system and speaking the language of evil. One of the main reasons is that this language's insidious methods have not yet been revealed. Although thousands of people around the world speak this language, no one mentions it, so its evil cannot be unmasked. Indeed, one of the main principles of this language is that it should not be unmasked. Satan's insidious system can continue only if secrecy is maintained, and only in secret can people continue to practice the evil based on this insidiousness. The fact that this universal language remains a secret is why so many follow satan with no qualms about committing evil.
Therefore, it is vital that satan's secret language of evil be brought out into the open. If that can be done, satan, with all his interference based on secrecy, will be unmasked and his methods will have no further effect on the lives of humans. He can deceive people only with these insidious methods; he can approach them only in unexpected places and spheres. Once more people came to know the methods he employs, his games would have no more effect—Allah willing.
In addition, we learn in the Qur'an that it is a believer's responsibility to stand up to evil and eradicate a morality that fosters evil: "Let there be a community among you who call to the good, and enjoin the right, and forbid the wrong. They are the ones who have success." (Surah Al 'Imran: 104) Allah tells us in the Qur'an how we are to purify our lower selves and oppose a belief system that supports satan's evil. The solution that will remove all the evil in the world is to practice the moral teachings of the Qur'an.
This book's purpose is to expose in detail satan's system that calls people to the secret practice of evil, to uncover its silent language and to show the ways to foil satan's traps. Yet another purpose is to remind individuals that they will be held responsible before Allah for evil they commit, both in secret and openly and to invite all people to practice the moral teachings of the Qur'an.
Abandon wrong action, outward and inward. Those who commit wrong action will be repaid for what they perpetrated. (Surat al-An'am: 120)
