يَوْمَ هُم بَارِزُونَ لَا يَخْفَى عَلَى اللَّهِ مِنْهُمْ شَيْءٌThe Day when they will come out, nothing of them will be hidden from Allah.means, they will all appear in the open, with nothing to give them shelter or shade, or cover them. Allah says:يَوْمَ هُم بَارِزُونَ لَا يَخْفَى عَلَى اللَّهِ مِنْهُمْ شَيْءٌ (The Day when they will come out, nothing of them will be hidden from Allah).meaning, everything will be equally known to Him.لِّمَنِ الْمُلْكُ الْيَوْمَ لِلَّهِ الْوَاحِدِ الْقَهَّارِWhose is the kingdom this Day It is Allah's, the One, the Irresistible!We have already mentioned the Hadith of Ibn Umar, may Allah be pleased with him, that Allah will roll up the heavens and the earth in His Hand and will say,أَنَا الْمَلِكُ أَنَا الْجَبَّارُ أَنَا الْمُتَكَبِّرُ أَيْنَ مُلُوكُ الاَْرْضِ أَيْنَ الْجَبَّارُونَ أَيْنَ الْمُتَكَبِّرُونَ "I am the King, I am the Compeller, I am the Proud, where are the kings of the earth? Where are the tyrants? Where are the proud?" In the Hadith about the Trumpet, it says that Allah will take the souls of all of His creatures, and there will be none left but Him Alone, with no partner or associate. Then He will say,"Whose is the kingdom today" three times,and He will answer Himself by saying, لِلَّهِ الْوَاحِدِ الْقَهَّار (It is Allah's, the One, the Irresistible!)meaning, He is the Only One Who has subjugated all things.الْيَوْمَ تُجْزَى كُلُّ نَفْسٍ بِمَا كَسَبَتْ لَا ظُلْمَ الْيَوْمَ إِنَّ اللَّهَ سَرِيعُ الْحِسَابِ
