The Pronunciation Error in the Takbir in Prayer

The questioner:
Honorable Shaykh, may Allah grant you success, what is the ruling on these words in the takbir, "Allahu Akbar" and

The Shaykh:
"Wahid Warathah," but. It is not permissible in the language because "Allahu Akbar" is a subject and the nominative case is required, so if one says "Allahu Akbar" with a kasrah, this is a pronunciation error, but it does not change the meaning,

The questioner:
and we say "Allah."

The Shaykh:
"Akbar" with a waw. He says "Allahu Akbar" with a hamsah (breath sound), and if one says "Allahu Akbar" among the common people, there is no harm, to the point that they said this is a waw in the language. Say it with a hamsah, a waw is permissible, "Allahu Akbar." The important thing is that if he says "Allahu Akbar," it is forgiven, yes, and if he does not know, say to him "Allahu Akbar," he knows this thing. But if he says "Allahu Akbar" with a kasrah, it does not invalidate the prayer. Yes.

The questioner:
And the phrase "Allahu Akbar" is with a kasrah on the kaf, not with a sukun. "Allahu Akbar" is said with a kasrah on the kaf.

The Shaykh:
How? How? Or do you lower it, and "Allahu Akbar."

The questioner:
It will cost you and you will be stuck.

The Shaykh:
Hmm?

The questioner:
And not with a sukun, "Kathra al-Kafir."

The Shaykh:
Look. Yes. Hm? If there is a nasal sound, meaning his tongue has a nasal sound, there is no harm, this is what he is able to do, but if there is no nasal sound, it is clear because this is not, but it does not change the meaning, a pronunciation error that does not change the meaning, like "Allahu Akbar," it does not change the meaning, so it is disliked, yes.
