Malik yawmid-Din is translated as "The King of the Day of Judgment". This is a phrase that appears in the Surah Al-Fatihah, the first chapter of the Qur'an. It is a declaration of belief in the sovereignty of Allah over the Day of Judgment, and an acknowledgement of the power and authority that Allah holds in determining the fate of all human beings. The phrase emphasizes the importance of seeking Allah's guidance and mercy in this life, in order to be prepared for the ultimate judgment that awaits us all in the afterlife.
