Treatment for one afflicted with intrusive thoughts in ablution and prayer

Question:
May Allah reward you, our Shaykh, and increase you in knowledge, and may He reward you for the Muslims with good. This questioner asks, saying: I am a man afflicted with waswas (intrusive thoughts) and various obsessions. Satan comes to me during my wudu' (ablution) and my salah (prayer). I say the takbir (Allahu Akbar) many times over. And when I perform the tashahhud, he enters and tells me that I have not done the tashahhud, have not sent blessings upon the Prophet, have not said the takbir, and have not glorified Allah. What is the guidance, for this matter worries me, keeps me awake at night, and has affected my life?

Answer:
If you feel that, seek refuge in Allah from the accursed Shaytan. He is the All-Hearing, the All-Knowing. Seek refuge in Allah; that is the first matter. The second matter is that you do not pay attention to the waswas, but rather reject it completely and do not interact with it. It will go away from you, if Allah wills, if you do these two things: seek refuge in Allah from the accursed Shaytan when you feel the waswas, and do not interact with it or pay attention to it. Reject it completely, and proceed with your worship, your prayer, and your ablution. Yes.
