[25].Surah Al-Furqan [The Criterion]: Ayat 25-26

২৫. সেদিন আকাশ মেঘমালাসহ বিদীর্ণ হবে এবং সেদিন ফেরেশতাদের নামিয়ে দেয়া হবে,
২৬. সেদিন সত্যিকার রাজত্ব হবে দয়াময় আল্লাহর এবং কাফেরদের পক্ষে দিনটি হবে কঠিন।  

Ayat 25. And (remember) the Day when the heaven shall be rent asunder with clouds, and the angels will be sent down, with a grand descending.

Ayat 26. The sovereignty on that Day will be the true (sovereignty), belonging to the Most Beneficent (Allah), and it will be a hard Day for the disbelievers (those who disbelieve in the Oneness of Allah Islamic Monotheism).

[Tafseer] of Ayat 25. The Day the heaven shall be rent asunder with clouds, and angels shall be sent down, descending (in ranks), - It will be a new world, and the symbolism to describe it must necessarily draw upon our present experience of the finest things in nature. The sky, which now appears remote and un-peopled, will be rent asunder. There will appear clouds of glorying-angels and spiritual Lights of all grades and ranks-and the true majesty and goodness of Allah will be visible as it should be in reality, and as it is not now, on account of "our muddy vesture of decay". [Tafseer] of Ayat 26. That Day, the dominion as of right and truth, shall be (wholly) for (Allah) Most Merciful: it will be a Day of dire difficulty for the Misbelievers.

Hazrat Ibn Umer (May Allah be pleased with him) reported: The Messenger of Allah [SAWW](PBUH) said, "Mankind will stand before Allah, the Rubb of the worlds (on the Day of Resurrection), some of them will stand submerged in perspiration up to half of their ears".     

[Al-Bukhari Book 06, Chapter 60, Hadith # 460].

Lesson : as mentioned above in Surah Al-Furqan Ayat 26."it will be a hard Day for the disbelievers" This Hadith gives us a glimpse of the horrible scene of the Resurrection when people who disobey will stand in awe before Allah.
