The Day they come forth nothing concerning them will be concealed from (40:16)

Almuntakhab Fi Tafsir Alquran Alkarim

The Day when they are fully exposed within and without and none of their aspects or secrets bearing reference to the way they conducted themselves in life, is but to Allah fully disclosed. There and then to whom belong the domination and the supreme controlling power and absolute and independent authority but to Allah, AL-Wahid and AL-Gahhar the One and only and the All Powering

Tafseer Tafheem-ul-Quran by Syed Abu-al-A'la Maududi

(40:16) the Day when they will emerge and nothing of them shall be hidden from Allah. (On that Day they will be asked): 'Whose is the kingdom today?' *27 (The whole world will cry out): 'It is Allah's, the One, the Overpowering.'

*27) That is, "Thougth in the world many vain and self-conceited people publicly proclaimed to be the kings and sovereigns, whose, in fact, is the Kingdom today? Who is the Owner of the powers and authority and Whose is the Command?" If a person hears these words in his right senses, he will be filled with terror, no matter how mighty a king or dictator he might be posing himself to be, and will immediately come to his senses. Here the mention of an historical event will not be out of place. When the Samanid ruler, Nasr bin Ahmad (301-331 A.H.), entered Nishapur, he held a court and after ascending the throne desired that the proceedings be started with recitation from the Holy Qur'an. At this an elderly pious man came forward and recited this very section of this Surah. When he came to this verse, Nasr was struck with awe; he descended the throne trembling, took off the crown and fell down in prostration, saying: "O my Lord, Kingdom is Thine, not mine!"

وہ دن جبکہ سب لوگ بے پردہ ہوں گے، اللہ سے ان کی کوئی بات بھی چھپی ہوئی نہ ہو گی (اُس روز پکار کر پوچھا جائے گا) آج بادشاہی کس کی ہے؟ (سارا عالم پکار اٹھے گا) اللہ واحد قہار کی
