The Ruling on Mispronunciation in the Takbir in Prayer

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

The Shaykh:
"Allah Akbar" is a mispronunciation. It is not permissible in the language because "Allah Akbar" is a subject and a predicate, and it must be in the nominative case. So if one says "Allah Akbar," it is a mispronunciation, but it does not change the meaning. It is disliked, but it does not change the meaning.

The questioner:
And the phrase "Allah Akbar" with a waw.

The Shaykh:
He says "Allah Akbar" with a hamzah, and if he says "Allah Akbar" as is common among the general people, there is no harm. In fact, they have said that this is found in the language. Changing the hamzah to a waw is permissible, "Allah Akbar." The important thing is that if he says "Allah Akbar," there is leniency in it, but he should be taught. One should tell him, "Say 'Allah Akbar,'" and he should learn this. But if he says "Allah Akbar," it does not invalidate the prayer. Yes.

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

The Shaykh:
How? A kaf with a sukun. Or does it become "Allah Akbar"?

The questioner:
With a kasrah on the kaf, not with a sukun.

The Shaykh:
Hmm?

The questioner:
Not with a sukun, but with a kasrah on the kaf.

The Shaykh:
Here, how is it possible? Yes. Hmm? If he has a speech impediment, meaning his tongue has a speech impediment, then there is no harm. This is for the one who is able to do so. But if he does not have a speech impediment, it should be made clear to him that this is not correct. However, it does not change the meaning. It is a mispronunciation that does not change the meaning, like "Allah Akbar." It does not change the meaning, so it is disliked with it.
