What is the name of the Sura that includes the verses: "O Allah, You are my Lord, there is no god but You; upon You I rely, and You are the Lord of the Great Throne. There is no might nor power except with Allah, the Exalted, the Most Great. What Allah wills occurs, and what He does not will does not occur. I know that Allah is over all things competent"?

What was mentioned is not from the Holy Quran, nor is it an authentic Hadith with this exact wording and arrangement. However, there are Hadiths with this meaning and similar wordings. Among them is what appeared in Kanz al-Ummal with the wording: "O Allah, You are my Lord, there is no god but You. I have put my trust in You, and You are the Lord of the Mighty Throne. What Allah wills will be, and what He does not will will not be. There is no might or power except with Allah, the Most High, the Most Great. I know that Allah is over all things competent, and that Allah has encompassed all things in knowledge. O Allah, I seek refuge in You from the evil of my soul and from the evil of every creature whose forelock You hold. Indeed, my Lord is on a straight path." And it was narrated in Amal al-Yawm wa al-Laylah by Ibn al-Sunni with the wording: "Whoever says in the morning and in the evening: 'My Lord is Allah, upon Him I have relied, and He is the Lord of the Mighty Throne. There is no god but Allah, the Most High, the Most Great. What Allah wills will be, and what He does not will will not be. I know that Allah is over all things competent, and that Allah has encompassed all things in knowledge,' then dies, will enter Paradise."
