Allah's name Al-Malik (The King, The Sovereign) in the Holy Quran

﴿فَتَعَٰلَى ٱللَّهُ ٱلۡمَلِكُ ٱلۡحَقُّۗ وَلَا تَعۡجَلۡ بِٱلۡقُرۡءَانِ مِن قَبۡلِ أَن يُقۡضَىٰٓ إِلَيۡكَ وَحۡيُهُۥۖ وَقُل رَّبِّ زِدۡنِي عِلۡمٗا ﴾ [Ṭā-Hā: 114]

(114) So high [above all] is Allah, the Sovereign, the Truth. And, [O Muhammad], do not hasten with [recitation of] the Qur'an before its revelation is completed to you, and say, "My Lord, increase me in knowledge."

Surah: Ṭā-Hā - Verse: 114 - Juz: 16 - Page: 320

﴿فَتَعَٰلَى ٱللَّهُ ٱلۡمَلِكُ ٱلۡحَقُّۖ لَآ إِلَٰهَ إِلَّا هُوَ رَبُّ ٱلۡعَرۡشِ ٱلۡكَرِيمِ ﴾ [Al-Mu’minūn: 116]

(116) So exalted is Allah, the Sovereign, the Truth; there is no deity except Him, Lord of the Noble Throne.

Surah: Al-Mu’minūn - Verse: 116 - Juz: 18 - Page: 349

﴿يَوۡمَئِذٖ يُوَفِّيهِمُ ٱللَّهُ دِينَهُمُ ٱلۡحَقَّ وَيَعۡلَمُونَ أَنَّ ٱللَّهَ هُوَ ٱلۡحَقُّ ٱلۡمُبِينُ ﴾ [An-Nūr: 25]

(25) That Day, Allah will pay them in full their deserved recompense, and they will know that it is Allah who is the perfect in justice.

Surah: An-Nūr - Verse: 25 - Juz: 18 - Page: 352

﴿ذَٰلِكَ بِأَنَّ ٱللَّهَ هُوَ ٱلۡحَقُّ وَأَنَّ مَا يَدۡعُونَ مِن دُونِهِ ٱلۡبَٰطِلُ وَأَنَّ ٱللَّهَ هُوَ ٱلۡعَلِيُّ ٱلۡكَبِيرُ ﴾ [Luqmān: 30]

(30) That is because Allah is the Truth, and that what they call upon other than Him is falsehood, and because Allah is the Most High, the Grand.

Surah: Luqmān - Verse: 30 - Juz: 21 - Page: 414

﴿سَنُرِيهِمۡ ءَايَٰتِنَا فِي ٱلۡأٓفَاقِ وَفِيٓ أَنفُسِهِمۡ حَتَّىٰ يَتَبَيَّنَ لَهُمۡ أَنَّهُ ٱلۡحَقُّۗ أَوَلَمۡ يَكۡفِ بِرَبِّكَ أَنَّهُۥ عَلَىٰ كُلِّ شَيۡءٖ شَهِيدٌ ﴾ [Fuṣṣilat: 53]

(53) We will show them Our signs in the horizons and within themselves until it becomes clear to them that it is the truth. But is it not sufficient concerning your Lord that He is, over all things, a Witness?

Surah: Fuṣṣilat - Verse: 53 - Juz: 25 - Page: 482
