﴿ فَإِن تَوَلَّوْا۟ فَقُلْ حَسْبِىَ ٱللَّهُ لَآ إِلَٰهَ إِلَّا هُوَ ۖ عَلَيْهِ تَوَكَّلْتُ ۖ وَهُوَ رَبُّ ٱلْعَرْشِ ٱلْعَظِيمِ ﴾

“But if those [who are bent on denying the truth] turn away, say: "God is enough for me! There is no- deity save Him. In Him have I placed my trust, for He is the Sustainer, in awesome almightiness enthroned."”

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. 9128-129.
