quran:18:38 –

But as for me, He is Allah, my Lord, and I do not associate with my Lord anyone.  

But lo (lākinnā is actually ˹made up of˺ lākin anā, ‘but I … ’, where the hamza vowel has ˹either˺ been transferred onto the nūn ˹of lākin˺, or omitted ˹altogether˺ with the nūn assimilated with the like of it) He ˹is˺ (huwa, this is the pronoun of the ˹subject˺ matter ˹to be stated˺ and is clarified by the sentence that follows it: the meaning ˹in other words˺ is ‘˹But, it is that˺ I say that ˹He is˺’) God, my Lord, and I do not ascribe any partner to my Lord.
القرآن:١٨:٣٨ –

لَٰكِنَّا هُوَ اللَّهُ رَبِّي وَلَا أُشْرِكُ بِرَبِّي أَحَدًا  

{لكنا} أصله لكن أنا نقلت حركة الهمزة إلى النون أو حذفت الهمزة ثم أدغمت النون في مثلها {هو} ضمير الشأن تفسره الجملة بعده والمعنى أنا أقول {الله ربي ولا أشرك بربي أحدا}.
