Key Verses

1. 13:9Ar-Rad
   عَٰلِمُ ٱلۡغَيۡبِ وَٱلشَّهَٰدَةِ ٱلۡكَبِيرُ ٱلۡمُتَعَالِ
   He is the Knower of the Invisible and the Visible, the Great, the High Exalted.
   In context

   This is because He, may He be glorified, knows about everything that is not perceived by His creation as well as everything that is perceived by them. He is the Majestic in His attributes, names and actions. The Supreme over every creation of His in His self and attributes.

2. 22:62Al-Hajj
   ذَٰلِكَ بِأَنَّ ٱللَّهَ هُوَ ٱلۡحَقُّ وَأَنَّ مَا يَدۡعُونَ مِن دُونِهِۦ هُوَ ٱلۡبَٰطِلُ وَأَنَّ ٱللَّهَ هُوَ ٱلۡعَلِيُّ ٱلۡكَبِيرُ
   That is because Allah, He is the True, and that whereon they call instead of Him, it is the false, and because Allah, He is the High, the Great.
   In context

   The aforementioned, i.e. entering the night into the day and the day into the night, is because Allah is truly existent, and so His religion is the truth, His promise is also true and His helping the believers is also true. The idols that the idolaters worship instead of Allah are false and have no basis.

3. 31:30Luqman
   ذَٰلِكَ بِأَنَّ ٱللَّهَ هُوَ ٱلۡحَقُّ وَأَنَّ مَا يَدۡعُونَ مِن دُونِهِ ٱلۡبَٰطِلُ وَأَنَّ ٱللَّهَ هُوَ ٱلۡعَلِيُّ ٱلۡكَبِيرُ
   That (is so) because Allah, He is the True, and that which they invoke beside Him is the False, and because Allah, He is the Sublime, the Great.
   In context

   That organisation and decree bears testimony to Allah alone being true; He is true in His being, attributes and actions. It also bears testimony to everything that the idolaters worship being unfounded falsehood, and that Allah is the Exalted in His being and His attributes over all His creation; there is none higher than Him, and He is greater than everything.

4. 34:23SabaCommand
   وَلَا تَنفَعُ ٱلشَّفَٰعَةُ عِندَهُۥٓ إِلَّا لِمَنۡ أَذِنَ لَهُۥۚ حَتَّىٰٓ إِذَا فُزِّعَ عَن قُلُوبِهِمۡ قَالُواْ مَاذَا قَالَ رَبُّكُمۡۖ قَالُواْ ٱلۡحَقَّۖ وَهُوَ ٱلۡعَلِيُّ ٱلۡكَبِيرُ
   No intercession availeth with Him save for him whom He permitteth. Yet, when fear is banished from their hearts, they say: What was it that your Lord said? They say: The Truth. And He is the Sublime, the Great.
   In context

   And intercession in His presence does not benefit except for one whom Allah gives permission, and Allah does not give permission to intercede except for whom He is pleased, due to His greatness.

5. 40:12GhafirWarning
   ذَٰلِكُم بِأَنَّهُۥٓ إِذَا دُعِيَ ٱللَّهُ وَحۡدَهُۥ كَفَرۡتُمۡ وَإِن يُشۡرَكۡ بِهِۦ تُؤۡمِنُواْۚ فَٱلۡحُكۡمُ لِلَّهِ ٱلۡعَلِيِّ ٱلۡكَبِيرِ
   (It is said unto them): This is (your plight) because, when Allah only was invoked, ye disbelieved, but when some partner was ascribed to Him ye were believing. But the command belongeth only to Allah, the Sublime, the Majestic.
   In context

   That punishment which you are punished with is because when Allah was called upon and no partner was associated with Him, you disbelieved in Him and made partners for Him. And when partners were worshipped alongside Allah, you believed. So the judgment is with Allah alone, High with His essence, decree and domination, the Great.
