The ruling on addressing people in formal Arabic

The questioner:
Speaking to people in formal Arabic, O Shaykh.

The Shaykh:
Inform people of what they know. Address them in their language and make it known to them. He speaks with them and makes it known to them, without forcing it. He says: Address them with the customary speech that they know and understand. Inform people of what they know. Do you love that Allah and His Messenger should be lied about? Address them with what suits them and what they understand, so that matters do not become confused for them.

The presenter:
May Allah bless you. The imam began with what was easy for him of reciting the loud prayers and began to bow, raising his hands, but he did not say the takbir. So one of the ma'mum (those praying behind the imam) thought that he had forgotten the verse that followed, so he recited it for him. The imam completed the recitation and did not raise his hands.

The Shaykh:
It does not harm him. It does not harm him. But if he intends to say the takbir, he says it, even if he leaves out some of the verses. And it is obligatory for him to recite all the verses.

The presenter:
He is honorable. He intended, if he comes.

The Shaykh:
If you recite, it does not harm.

The presenter:
He did not know that it changed.

The Shaykh:
No, it does not harm her.
