Surah Al-Furqan — Ayah 26 (25:26)
ٱلۡمُلۡكُ يَوۡمَئِذٍ ٱلۡحَقُّ لِلرَّحۡمَٰنِۚ وَكَانَ يَوۡمًا عَلَى ٱلۡكَٰفِرِينَ عَسِيرٗا ٢٦
English translation (Saheeh International)
True sovereignty, that Day, is for the Most Merciful. And it will be upon the disbelievers a difficult Day.
Brief commentary
Kingdom, which is the true and established kingdom, on the Day of Judgment will be for the Merciful, may He be glorified. That day will be difficult for the disbelievers as opposed to the believers for whom it will be easy.
