Does a mother sin if she finds difficulty in pronouncing some Qur'anic words with their correct diacritics without altering the meaning, and should she continue memorizing or stop?

It is necessary to correct the recitation of the Qur’an and to pronounce words and vowels correctly. It is not permissible to recite with incorrect vowels, even if they do not change the meaning. If the mother is able to learn and correct her mistakes, she must do so and will be sinful if she deliberately continues to recite incorrectly. However, if she is unable to learn, then if most of her recitation is melodious (mispronounced), she should abandon it and strive to learn and correct Al-Fatiha. If most of it is correct and she cannot correct the rest, there is no harm in her reciting, but in a low voice, and she will have solace and eagerness for recitation. She should start anew under the supervision of a teacher and not stop trying to memorize and correct, because the Qur’an is made easy for whoever desires it.
