What is the ruling on prayer when I feel as if my Qareen (jinn companion) is speaking on my tongue with all the invocations within the prayer, and is it true that among the symptoms of the Qareen is that it speaks through the tongue of the afflicted person?

We advise you to turn your mind away from the whispers of the Qareen (companion jinn) and occupy your time with good deeds. You can perform Ruqyah Shariah (Islamic exorcism) or consult doctors. The Qareen is often a source of evil, whispering bad thoughts, making one forget good things, and promising and instilling arrogance. So, do not pay attention to its doubts that you did not recite the Adhkar (supplications) in prayer; rather, be certain that you did. Be diligent in performing congregational prayers, keeping company with righteous people, cooperating in righteousness and piety, and enjoining truth and patience, for "the hand of Allah is with the community," and "the wolf only eats from the sheep that stray far."
