Why were the words "yashhadu" (he bears witness) and "ya'lamu" (he knows) followed by "inna" in the first verse of Surat Al-Munafiqun, when the rule requires them to be followed by "an" similar to "ashhadu an," and unlike the verb "qala" (he said) which is followed by "inna"?

The hamza of (إِنَّ - inna) is broken when the verb is connected to the lam (لَ - la), as in the Almighty's saying: (وَاللَّهُ يَعْلَمُ إِنَّكَ لَرَسُولُهُ وَاللَّهُ يَشْهَدُ إِنَّ الْمُنَافِقِينَ لَكَاذِبُونَ - And Allah knows that you are indeed His Messenger, and Allah testifies that the hypocrites are indeed liars). It is also broken if the speech after the verb of saying recounts the exact wording of the spoken statement, such as: (قَالَ إِنِّي عَبْدُ اللَّهِ - He said: "Indeed, I am a servant of Allah"). The hamza of (أَنَّ - anna) is opened after the verb of saying if the exact recounting is not intended.
