quran:9:129 –

But if they turn away, ˹O Muhammad˺, say, "Sufficient for me is Allah; there is no deity except Him. On Him I have relied, and He is the Lord of the Great Throne."  

So if they turn away, ˹refraining˺ from believing in you, say: ‘God suffices me. There is no god except Him. Upon Him I rely, in Him have I put my trust, and in none other, and He is the Lord of the Tremendous Throne’ (al-‘arsh al-azīm), the kursī, which is singled out for mention because it is the greatest of all things created. Al-Hākim reported in al-Mustadrak ˹by way of an isnād˺ from Ubayy b. Ka‘b that he ˹Ubayy˺ said: ‘The last verse to be revealed was ˹from˺, Verily there has come to you a messenger… to the end of the sūra’ ˹sc. Q. 9:128-129˺. Meccan, except for verses 40, 94, 95 and 96, which are Medinese; it consists of 109 or 110 verses, and was revealed after ˹sūrat˺ al-Isrā’.
القرآن:٩:١٢٩ –

فَإِنْ تَوَلَّوْا فَقُلْ حَسْبِيَ اللَّهُ لَا إِلَٰهَ إِلَّا هُوَ ۖ عَلَيْهِ تَوَكَّلْتُ ۖ وَهُوَ رَبُّ الْعَرْشِ الْعَظِيمِ  

{فإن تولَّوا} عن الإيمان بك {فقل حسبي} كافيّ {الله لا إله إلا هو عليه توكلت} به وثقت لا بغيره {وهو ربُّ العرش} الكرسي {العظيم} خصه بالذكر لأنه أعظم المخلوقات، وروى الحاكم في المستدرك عن أبيّ بن كعب قال: آخر آية نزلت {لقد جاءكم رسول} إلى آخر السورة.

quran:27:26 –

Allah - there is no deity except Him, Lord of the Great Throne."  

God — there is no god except Him, the Lord of the Mighty Throne’ (this clause constitutes an ˹independent˺ new sentence, which is a eulogy comprising ˹praise of˺ the Throne of the Compassionate One to counter the ˹description of the˺ throne of Bilqīs: between the two, however, is an unfathomable difference).
القرآن:٢٧:٢٦ –

اللَّهُ لَا إِلَٰهَ إِلَّا هُوَ رَبُّ الْعَرْشِ الْعَظِيمِ ۩  

{الله لا إله إلا هو رب العرش العظيم} استئناف جملة ثناء مشتمل على عرش الرحمن في مقابلة عرش بلقيس وبينهما بون عظيم.
