I know, that there are three conditions, that an Ahruf/Qiraat is accepted by the scholars. One is Arabic Grammer, one is mass transmission and one ist conformity with one of the Uthmanic mushafs. My question: Is every Ahruf confirmed to fulfill the last condition with the mushafs? Or are there some, which are not proven to confirm it?
Because this statement led me to this question: „Finally note that expecting any reading of the Qur'an to fully coincide with the rasm of al-Moshaf is a wrong expection as the rasm was kept due to the fact that many scholars conisdered it as canonical nevertheless they knew it is not going ahead with the correct recitation as all scholars agree that the Qur'an is and has to be transmitted orally not via a scripture nor based on it.“ Source: https://islam.stackexchange.com/questions/30409/how-to-explain-the-recitation-لَئ%D9%90نْ-انجــينا-verse-6-63-by-al-azami-in-his-bo
Is there a misunderstanding for this statement? When is it true, that not every recitation is confirmed, what would that mean for the third condition, the importance of it, would be gone? Or is every recitation confirmed to fulfill the condition?
Allah knows best.
