What is the ruling on one who is afflicted with misgivings regarding the articulation points of letters (makharij al-huruf) in the first and last Tashahhud, and in Surat al-Fatiha, to the extent that they can no longer pronounce certain letters or forget how to pronounce a letter, which prolongs their prayer in every obligatory prayer?

The cure for obsessive thoughts is to turn away from them and not pay attention to them. Therefore, you should pray without being concerned by them, and recite in a normal manner, unconcerned by what Satan casts. Whenever he makes you imagine that you did not pronounce a letter correctly, do not pay attention to this illusion, and continue with your prayer until Allah grants you healing.
