Mispronouncing a Word or a Letter of Prayer
Issue No.914- If a person does not know a certain word of al-fātiḥa or the sūrah, or other dhikrs in the prayer, or does not correctly pronounce Arabic linguistic signs like "fatha" or "kasra", or mispronounces one letter instead of another like “Z” for “Ḍ” in a way that it would be counted wrong according to the Arabic language, his prayer is void.
