[21].Al-Anbiya [The Prophets]: Ayat 104-106

Ayat 104. And (remember) the Day when We shall roll up the heavens like a scroll rolled up for books, as We began the first creation, We shall repeat it, (it is) a promise binding upon Us. Truly, We shall do it.

Ayat 105. And indeed We have written in Zabûr (Psalms) [i.e. all the revealed Holy Books the Taurat (Torah), the Injeel (Gospel), the Qur'an] after (We have already written in) Al-Lauh Al-Mahfûz (the Book, that is in the heaven with Allah), that My righteous slaves shall inherit the land (i.e. the land of Paradise).

Ayat 106. Verily, in this (the Qur'an) there is a plain Message for people who worship Allah (i.e. the true, real believers of Islamic Monotheism who act practically on the Qur'an and the Sunnah legal ways of the Prophet  [SAWW](PBUH).

[Tafseer] The world—the universe—as we know it, will be folded up like a scroll of parchment, for it will have done its work. If Allah created all this world out of nothing, He can create an entirely new heaven and a new earth, on a plane of which we can form no conception in our present life. And He will do so, for that is His promise. Some Commentators understand Sijill to be the name of the Recording Angel who closes the Book of a man's Deeds after the man's death. Before this We wrote in the Psalms, after the Message (given to Moses): My servants the righteous, shall inherit the earth." Zabur. the Book of the Psalms of David. The name of David is expressly mentioned in connection with the Zabur in 4:163 and 17:55, although there the indefinite article is applied to the word as meaning a Book of Scripture. See Psalms 25:13, "his seed shall inherit the earth": 37:11, "the meek shall inherit the earth" (quoted by Jesus in Matt. 5:5); and 37:29, "the righteous shall inherit the land.". The same promise occurs in the Pentateuch, Exod. 32:13, "they shall inherit it (the land) forever." Verily in this (Quran) is a Message for people who would (truly) worship Allah. The culmination of Allah's Revelation is in the Quran, which confirms previous scriptures, corrects the errors which men introduced into them, and explains many points in detail for all who seek right worship and service to Allah— whether they inherit the previous Books ("People of the Book") or not. It is a universal Message. 

Hazrat Samurah bin Jundub (May Allah be pleased with him) reported: The Messenger of Allah [SAWW](PBUH) said, "Among the people of Hell are there those who will be emersed in fire to their ankles, some to their knees, some to their waists, and some to their throats".

[Muslim Book 40, Chapter 12, Hadith # 6815].

Lesson : as mentioned above in Surah Al-Anbiya Ayat 104."And (remember) the Day when We shall roll up the heavens like a scroll rolled up for books," This Hadith tells us that the inhabitants of Jannah will be classified into different categories and enjoy different kinds of luxuries according to their merits. A similar classification will also be made in the inhabitants of Hell and they will suffer torments according to their misdeeds.
