Does doubting the correctness of one's recitation due to self-whispers necessitate repeating the recitation outside of prayer?

We advise you to turn away from whisperings (waswas) and thoughts and not to pay attention to them, for they do not harm nor do they necessitate re-reading. You must strive against them and get rid of them, and guard your thoughts to ponder over what benefits you in your religious and worldly affairs. Be sure to bring your heart to the recitation of the Qur'an, and to reflect on the verses and ponder their meanings, so that your benefit and reward may be more complete.
