Allah the Exalted said: << فما كان جواب قومه إلآ أن قالوا اقتلوه أو حرقوه فأنجاه الله من النار إن في ذلك لأيات لقوم يؤمنون >

Allah the Exalted said in the story of Ibrahim:

But the answer of his people

فَمَا كَانَ جَوَابَ قَوْمِهِ

[An-Naml 27:56]

" Because, according to the author's opinion, this clause is an interjection. From where? From his saying: [Al-Ankabut: 18] up to this point is an interjected clause. Did you understand? This is the view of the author, Ibn Jarir, and most of the exegetes. Some exegetes said that the entire speech is from Ibrahim and that there is nothing interjected in it. Ibn Kathir chose this view and said that it is all from the speech of Ibrahim.
The student: It is difficult to understand...

The Shaykh : What is the nature of the difficulty?
The student: If it were from the speech of Ibrahim, it would be problematic, for the mercy is not for Ibrahim, but it is for Allah, Mighty and Majestic.

The Shaykh : ... Well, is it not permissible for the Prophet to say it? Because, according to the opinion of these people, even the Messenger said it. They think that this is from the speech of the Messenger (peace and blessings be upon him). Yes, it is from the speech of Allah. They see that it is from the speech of Allah addressing the disbelievers of Quraysh. Now, let us look at the first one: If someone were to say that there is a problem with this, we would say there is no problem, because there were nations before Ibrahim, right? And His saying: [Al-Ankabut: 18].
