From the stories of Al-Allaamah Rabee Bin Haadee–how to repel shaytaan’s waswaas
Al-Allaamah Rabee Bin Haadee Al-Madkhalee (may Allaah preserve him) said:
The was-waas (whispering of shaytaan) a person comes across can be about Allaah, the Messenger, paradise and hell fire, or it can be about inner evil thoughts that violates Eemaan; so what is its remedy? The person should say: [أعوذ بالله من الشيطان] – [I seek refuge in Allaah from shaytaan]. He seeks refuge in Allaah from shaytaan or he says: [آمنت بالله ورسله ]—[I believe in Allaah and His Messengers], and at the same time he believes that this (waswaas) cannot harm him and that (repelling it) is unadulterated Eemaan. This is a testimony from the Messenger (sallal-laahu-alayhi-wasallam) that this whispering (of shaytaan) does not harm and (repelling it) is pure and clear Eemaan.
This is the most severe weapon against shaytaan because (this waswaas) is from his plots; and because he sees that the believer is focused in worship, sincerity and truthfulness, so he puts him to trial through whisperings in his salaah, in his creed and in this and that. Therefore, it is obligatory that one does not give way to these inner thoughts and he should cure them with these words (i.e. seeking refuge in Allaah from shaytaan etc). It is obligatory upon him to turn away from them and busy himself with other than these thoughts, and then he should seek aid and assistance in humiliating shaytaan and repelling him, saying: Indeed, the Messenger (sallal-laahu-alayhi-wasallam) testified for me that this is unadulterated and clear Eemaan.
I said to your brothers– amongst those you used to cure (from waswaas)—who said to me: ‘’I am a disbeliever.’’ So I said to him, ‘’How are you a disbeliever?’’ He said: ‘’I have inner thoughts about such and such.’’ I said to him, ‘’this does not harm you, rather say to shaytaan: Indeed, the Messenger (sallal-laahu-alayhi-wasallam) testified for me that it (i.e. this hatred and fight against this was-waas) is unadulterated Eemaan.’’ So do not be scared and never give it importance. Forget the likes of this (was-waas).’’ This is a remedy given by the Messenger of Allaah (sallal-laahu-alayhi-wasallam) to this Ummah. And if this (waswaas) was harmful, the Messenger (sallal-laahu-alayhi-wasallam) would have clarified it, but it does not harm Inshaa-Allaah.
