«والأصل في الخبر أن يلقى لإفادة المخاطب الحكم الذي تضمنته الجملة»
The normal purpose of a report is to inform the listener of the judgment expressed by the sentence.
“حَضَرَ الأَمِيرُ”
“The commander arrived.”
If the listener did not know of the arrival, the report communicates new information. This conveyance of the predicated content itself is fāʾidat al-khabar.
The speaker may simply intend to give information; advice, pride or blame must not be inferred without contextual evidence.
