اللَّـهُمَّ مَالِكَ الْمُلْكِ تُؤْتِي الْمُلْكَ مَن تَشَاءُ وَتَنزِعُ الْمُلْكَ مِمَّن تَشَاءُ وَتُعِزُّ مَن تَشَاءُ وَتُذِلُّ مَن تَشَاءُ ۖ بِيَدِكَ الْخَيْرُ ۖ إِنَّكَ عَلَىٰ كُلِّ شَيْءٍ قَدِيرٌ

Allaahumma Maalikul-mulki tu'til-mulka man tashaaa'u wa tanzi'ul-mulka mimman tashaaa'u wa tu'izzu man tashaaa'u wa tuzillu man tashaaa'u biyadikal-khair; innaka 'alaa kulli shai'in Qadeer.

O Allah, Owner 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.
