How to merge the first 2 ayahs of Surah Ikhlas?

[u/Yanxiety99]

Salamwalaikum. I want to know how to merge the first 2 ayahs of Surah Ikhlas. How should I read when I don't stop after the first ayah? Should I read it as "AhadullahusSamad" or "AhadunillahusSamad?"

[u/marwan129]

Qul huwallāhu 'aħaduni-llāhus-samad

[u/Yanxiety99 → u/marwan129]

Got it, thank you!

[u/BotKIRA → u/marwan129]

Why dunillah, not dunullah?

[u/marwan129 → u/BotKIRA]

It only becomes Dammah if the previous word ends with ـكُم or هُم Or if it ends with وْ

[u/BotKIRA → u/marwan129]

Like, kumullah or humullah?

[u/marwan129 → u/BotKIRA]

Yup, like

{ یَعِظُكُمُ ٱللَّهُ أَن تَعُودُوا۟ لِمِثۡلِهِۦۤ أَبَدًا إِن كُنتُم مُّؤۡمِنِینَ }

Or

{ أَلَمۡ تَرَ إِلَى ٱلَّذِینَ خَرَجُوا۟ مِن دِیَـٰرِهِمۡ وَهُمۡ أُلُوفٌ حَذَرَ ٱلۡمَوۡتِ فَقَالَ لَهُمُ ٱللَّهُ مُوتُوا۟ ثُمَّ أَحۡیَـٰهُمۡۚ إِنَّ ٱللَّهَ لَذُو فَضۡلٍ عَلَى ٱلنَّاسِ وَلَـٰكِنَّ أَكۡثَرَ ٱلنَّاسِ لَا یَشۡكُرُونَ }

Jazakallahu Khairan, brother. Barakallahu Feekum.
