Waswas in waswas-il-khannas means the one who whispers over and over again ........

The word waswas in waswas-il-khannas means the one who whispers over and over again, and waswasa means to whisper into someone's heart an evil suggestion over and over again in such a way or ways that the one who is being inspired may not feel that the whisperer is whispering an evil suggestion into his heart. Waswasah by itself suggests repetition just as zalzalah contains the meaning of repetitive movement. Since man is not tempted by just one attempt but effort has to be made over and over again to seduce and tempt him, such an attempt is called waswasah and the tempter waswas. As for the word khannas, it is derived from khunus, which means to hide after appearing and to retreat after coming into view. Since khannas is the intensive form, it would imply the one who behaves thus very frequently. Thus when once he fails in his attempt to whisper evil, he withdraws, then he again returns to make the second and the third and the next attempt over and over again.
Seeking refuge from the waswas means that the seeker after refuge himself seeks God's refuge from its evil, i.e. from the evil lest it should whisper some evil suggestion into his own heart. The second meaning is that the caller to Truth seeks God's refuge from the evil of the one who whispers evil suggestions into the hearts of the people against himself. It is not in his own power to approach all the people in whose hearts evil suggestions are being whispered against himself individually and remove the misunderstandings of every person. It is also not right and proper for him that he should give up his mission of inviting others to Allah and should devote all his tune and energy to removing the misunderstanding created by the whisperer and to answering their accusations. It is also below his dignity that he should stoop to the level of his opponents. Therefore, Allah has instructed the caller to Truth to seek only His refuge from the evil of the wicked people, and then to attend single-mindedly to his work of invitation and mission. For it is not for him to deal with them but for Allah, who is Sustainer of men, King of men, God of men.
Here, one should also understand that an evil suggestion is the starting point of evil act. When it affects a careless or heedless person, it creates in him a desire for evil. Then, further whisperings change the evil desire into an evil intention and evil purpose. When the evil suggestion grows in intensity, the intention becomes a resolution, which then culminates in the evil act. Therefore, the meaning of seeking God's refuge from the evil of the whisperer is that Allah should nip the evil in the bud.
If seen from another aspect, the order of the evil of the whisperers seems to be this: first. they incite one to open unbelief, polytheism, or rebellion against Allah and His Messenger, and enmity of the righteous (godly) people. If they fail in this and a person does enter Allah's religion, they misguide him to some innovation. If they fail in this too, they tempt him to sin. If they do not succeed even in this, they inspire the man with the suggestion that there is no harm in indulging in minor sins, so that if he starts committing these freely, he is over burdened with sin. If one escapes from this too, in the last resort they try that one should keep the true religion confined to oneself, and should do nothing to make it prevail, but if a person defeats all these plans, the whole party of the devils froth among men and jinn makes a common front against him incites and stirs up the people and makes them shower him with invective and accusation and slander, and defames him as widely as they can. Then, Satan comes to the believer and excites him to anger, saying: "It is cowardly of you to have borne all this insult: arise and clash with your opponents." This is the last and final device with Satan by which he tries to thwart the struggle of the caller to Truth and entangle him in difficulties and obstructions. If he succeeds in escaping from this too, Satan becomes powerless before him. About this same thing it has been said in the Qur'an: "If Satan ever excites you to anger, seek refuge with Allah."
