Therefore, the treatment of this disease is to seek refuge with Allah from Satan, the outcast, while performing ablution, during prayer and in all other situations. Whenever one feels the evil misgivings, he should seek refuge with Allah from Satan by saying: I seek refuge with Allah from Satan, the outcast, and one should have strong will and sincerity to get rid of these misgivings and should have hope in Allah (Most Exalted and Sublime be He).
If someone performs ablution he should not repeat his ablution due to devilish insinuations. Likewise, he should not repeat his prayer because of such insinuations. He should full trust that his ablution and prayer are valid and should not repeat any part of them due to Satan’s insinuations. For, if he inclines to obey Satan and repeats ablution or the prayer, then the enemy of Allah will prompt him with more evil temptations. Thus,whenever you perform ablution and you are confident that you have fulfilled all its requirements, then do not let doubt creep into your heart. Fear Allah and do not repeat some or all of its acts. Do not respond to the misgivings of Satan. The same should be done with regard to prayer which you should complete with no insinuations as having made mistakes therein. Do the same thing in every similar situation in which you withstand the misgivings of the enemy of Allah and beat him.
