Surah Al-Furqan, ayah 26

ٱلۡمُلۡكُ يَوۡمَئِذٍ ٱلۡحَقُّ لِلرَّحۡمَٰنِۚ وَكَانَ يَوۡمًا عَلَى ٱلۡكَٰفِرِينَ عَسِيرٗا ٢٦

Al-mulku yawma'idhinil-haqqu lir-rahmāni wakāna yawman 'alal-kāfirīna 'asīrā

True sovereignty, that Day, is for the Most Merciful. And it will be upon the disbelievers a difficult Day.
