Do I commit a sin if I don't correct a wrong recitation of the Qur'an by my neighbor who is learning from me?

Women must be taught the correct recitation of the Quran, without letting them recite incorrectly. They should be corrected gradually, for indeed, the one who teaches people good, Allah and His angels and the inhabitants of the heavens and the earths pray for him. And the Quran is the greatest of this good, and the best of people is he who learns the Quran and teaches it. Leaving her to recite incorrectly is considered forbidden deception.
