Surah Al-Fatiha 1:4 — translation and meaning

He is the Master of the day of Judgement, the day in which we will be brought back to life and repaid for what we have done, all of His creation will be held accountable for their actions and recompensed for them. On that day God will ask “To whom belongs the Kingdom today?” [Sūrah Ghafir: 16] No one, no matter how high his status, will answer, and then God will reply Himself, “to God, the One, the Overcomer” [Sūrah Ghafir: 16]
