The ways to protect faith against Satan

The devil attaches himself to the heart of the son of Adam when he is heedless and indifferent. He whispers evil to him - al-waswaas - but when he remembers Allah, the devil retreats. From this, it seems clear to us that the devil can enter the human body. He chooses the heart as his place, for the heart is like a commander and the organs are like his soldiers. So, if the devil masters the heart, the organs submit. But there are hearts surrounded by the walls of faith and a fortified citadel of piety, of which the remembrances of Allah - ad-dhikr - are the guards. The devil can only sneak in secretly, but he is quickly driven away by the guards - remembrances - and thus ends up outside the citadel, rejected and cast away. The purpose of this book is to provide an overview of the protective walls of faith and to teach their practice. In this way, the Muslim and his family are assured of complete protection against the devils among the jinn and mankind. May Allah assist us and make the good and sound practice easy for us, and may He protect us from evil.
