Al-Malik
As one of Allah's names, Al Malik represents His supreme authority and sovereignty over all things. It reminds Muslims that Allah is the ultimate ruler and owner of everything in the universe, and that all power and control belongs to Him alone.
قُلِ اللَّهُمَّ مَالِكَ الْمُلْكِ تُؤْتِي الْمُلْكَ مَن تَشَاء وَتَنزِعُ الْمُلْكَ مِمَّن تَشَاء وَتُعِزُّ مَن تَشَاء وَتُذِلُّ مَن تَشَاء بِيَدِكَ الْخَيْرُ إِنَّكَ عَلَىٰ كُلِّ شَيْءٍ قَدِيرٌ
Say: 'O Allah, Possessor of Sovereignty, You give sovereignty to whom You will and You take sovereignty away from whom You will. You honor whom You will and You humble whom You will. In Your hand is [all] good. Indeed, You are over all things competent.'" (Quran 3:26)
Abdullah b. 'Umar reported Allah's Messenger (ﷺ) saying: Allah, the Exalted and Glorious, would fold the Heavens on the Day of Judgment and then He would place them on His right hand and say:
" يَطْوِي اللَّهُ عَزَّ وَجَلَّ السَّمَوَاتِ يَوْمَ الْقِيَامَةِ ثُمَّ يَأْخُذُهُنَّ بِيَدِهِ الْيُمْنَى ثُمَّ يَقُولُ أَنَا الْمَلِكُ أَيْنَ الْجَبَّارُونَ أَيْنَ الْمُتَكَبِّرُونَ ثُمَّ يَطْوِي الأَرَضِينَ بِشِمَالِهِ ثُمَّ يَقُولُ أَنَا الْمَلِكُ أَيْنَ الْجَبَّارُونَ أَيْنَ الْمُتَكَبِّرُونَ " .
I am the Lord; where are the haughty and where are the proud (today)? He would fold the' earth (placing it) on the left hand and say: I am the Lord; where are the haughty and where are the proud (today)?
