Guidance for one who turns an obligatory prayer into a voluntary one due to intrusive thoughts

Question:
This questioner says: What is the ruling in the Shari'ah, in your view, regarding a person who prays the obligatory prayer, but when he feels, in the first or second rak'ah, that he has not given the prayer its due, he turns this prayer into a voluntary one, and then begins to perform the obligatory prayer?

Answer:
The believer should be cautious of intrusive thoughts. If he is certain that he has entered into a specific obligatory prayer, such as the midday or afternoon prayer, and then intrusive thoughts occur, he should dismiss these thoughts and continue in his prayer, completing it. This is because if he is lenient with intrusive thoughts, Satan will play with him and distract him.
Therefore, it is obligatory in such a case to be cautious of giving one's self its desires through intrusive thoughts. If he feels something, he should say: "I seek refuge in Allah from the accursed Satan," and continue, as long as he knows that he entered the prayer with clarity. He should complete it and not pay any attention to the intrusive thoughts, but rather dismiss them and warn against them, lest he open a door for Satan against him, causing him harm. Yes.
