Question:
May Allah reward you with good. What is the ruling in the Shari'ah regarding the intrusive thoughts and fleeting ideas that come to mind during prayer? May Allah reward you with good.

Answer:
A person must deal with these, keep his heart present in his prayer, and leave these intrusive thoughts. If he continues with them and does not deal with them, he will not be credited with any of his prayer except for the amount of it that he was conscious of, and he may not be credited with anything from it at all. However, he is not ordered to repeat the prayer, because he prayed in appearance, but in reality, no reward is written for him; he has nothing from his prayer except what he was conscious of, as came in the athar (report). And Allah, Glorified and Exalted is He, says: The spirit and essence of the prayer is the humility (khushu') before Allah, Glorified and Exalted is He. These intrusive thoughts, these ideas, and being preoccupied with the matters of this world contradict humility. So he prays with his body but not with his heart, or he prays with a body present and a heart absent. In that case, he is not credited with any of his prayer except what he was conscious of, and he may not be credited with anything from it, so it becomes a burden on him without benefit. This confirms for the person that he should seek refuge in Allah from the accursed Shaytan at the beginning of his prayer, after the opening takbir and before the recitation, with a present heart. If intrusive thoughts occur to him, he should turn his heart away from them, keep his heart present with Allah, and seek help from Allah, Mighty and Majestic. Yes.
