What is the cure for obsessive doubts in prayer and ablution?

Question : The questioner says: Honorable Shaykh, I am a young man who suffers from obsessive doubts (waswas) in prayer. I repeat the recitation of Surat al-Fatihah several times, and also the tashahhud, and also the wudu' (ablution), and also the menstrual cycle. Please advise us, may Allah reward you with good?

Answer : The benefit is that a person who begins to experience obsessive doubts in his purification, his prayer, or anything else, it is prescribed (mashru') for him to seek refuge in Allah, Glorified and Exalted is He, from this waswas, and to continue with what he is doing. For example, if he performs wudu' and then has doubts about whether he performed the obligatory acts, let him assume that he performed the obligatory acts and ignore this, even if his conscience alerts him or his soul tells him that you prayed without wudu'. Let him say, "There is no harm," and not pay attention to it. Likewise, if a person has waswas in prayer, in creed, or in anything else, his duty is to seek refuge in Allah and then stop, and then it will not harm him, if Allah wills.
