The ruling on the imam reciting with the seven canonical recitations that are not customary in his region

Question:
He says: Honorable Shaykh, there is an imam of a congregational mosque whom I know who knows some of the correct recitations among the seven, but he does not recite with them in the congregational prayer. Is that permissible for him?

Answer:
No, it is not permissible for him. He should recite with the Hafs recitation, because that is the one practiced in these lands. He should recite with the recitation that is practiced, and not cause confusion for the people by doing so, because the people are confused when they hear something they have not recited and do not know. However, if he is praying in a region where the people recite with the Warsh recitation or the Qunbul recitation, he should recite with the recitation that the people of that place or the people of that town recite with. That is what is required. And even if the prayer is valid, the prayer is valid.
A recitation that does not deviate from the Uthmanic script is valid. But if it causes confusion for the people who are not accustomed to this, it is not permissible to cause confusion for the people. They do not know or recognize this thing. They say, "He does not know how to recite the Warsh recitation," and they say, "He does not know how to recite; he is making a mistake." They do not know about this matter. But if he prays with people who know, students of knowledge who know this matter and no confusion arises for them, there is no harm. But with common people, people who do not know this matter, it causes confusion for them, and this is not permissible. As has passed to you, 'Ali (may Allah be pleased with him) said: "Inform the people of what they know. Do you want Allah and His Messenger to be lied about?"
Some people, if you recite the Warsh recitation to them, say, "I seek refuge in Allah. This is not the letter of the Qur'an." It is not permissible; he caused confusion for them, so they rejected it. This becomes a cause for the common person to reject something from the Qur'an, to reject something that is correct, and you are the cause of this. You are the one who heard something he does not know. Yes, inform the people of what they know. But if he is praying in a region where the people recite with this recitation, or if he is praying with students of knowledge who know this matter and do not reject it, there is no harm. Yes.
