Allah says:
﴿أَصْحَـبُ الْجَنَّةِ يَوْمَئِذٍ خَيْرٌ مُّسْتَقَرّاً وَأَحْسَنُ مَقِيلاً ﴾
(The dwellers of Paradise will, on that Day, have the best abode, and have the fairest of places for repose.) meaning, on the Day of Resurrection.
﴿لاَ يَسْتَوِى أَصْحَـبُ النَّارِ وَأَصْحَـبُ الْجَنَّةِ أَصْحَـبُ الْجَنَّةِ هُمُ الْفَآئِزُونَ ﴾
(Not equal are the dwellers of the Fire and the dwellers of the Paradise. It is the dwellers of Paradise that will be successful) (59:20). That is because the people of Paradise will ascend to lofty degrees and secure dwellings, so they will be in a place of safety, beauty and goodness,
﴿خَـلِدِينَ فِيهَا حَسُنَتْ مُسْتَقَرّاً وَمُقَاماً ﴾
(Abiding therein -- excellent it is as an abode, and as a place to rest in.) (25:76) The people of Hell will go down to the lowest levels and continual regret, with all kinds of punishments and torments.
﴿إِنَّهَا سَآءَتْ مُسْتَقَرّاً وَمُقَاماً ﴾
(Evil indeed it (Hell) is as an abode and as a place to rest in.)(25:66) means, how evil a dwelling place to look at, and how evil an abode in which to stay. Allah says:
﴿أَصْحَـبُ الْجَنَّةِ يَوْمَئِذٍ خَيْرٌ مُّسْتَقَرّاً وَأَحْسَنُ مَقِيلاً ﴾
(The dwellers of Paradise will, on that Day, have the best abode, and have the fairest of places for repose.) meaning, in return for what they have done of acceptable deeds, they will attain what they will attain and reach the status they will reach, in contrast to the people of Hell, who will not have even one deed to their credit that would qualify them to enter Paradise and be saved from the Fire. Allah points out the situation of the blessed in contrast to that of the doomed, who will not enjoy any goodness at all. Sa`id bin Jubayr said: "Allah will finish the Judgement halfway through the Day, and the people of Paradise will take their mid day rest in Paradise and the people of Hell in Hell. Allah says:
﴿أَصْحَـبُ الْجَنَّةِ يَوْمَئِذٍ خَيْرٌ مُّسْتَقَرّاً وَأَحْسَنُ مَقِيلاً ﴾
(The dwellers of Paradise will, on that Day, have the best abode, and have the fairest of places for repose.) `Ikrimah said, "I know the time when the people of Paradise will enter Paradise and the people of Hell will enter Hell. It is the time which in this world is the time when the late forenoon starts and people go back to their families to take a siesta. The people of Hell will go to Hell, but the people of Paradise will be taken to Paradise and will have their siesta in Paradise, and they will be fed the liver of a whale and they will all eat their fill. This is what Allah says:
﴿أَصْحَـبُ الْجَنَّةِ يَوْمَئِذٍ خَيْرٌ مُّسْتَقَرّاً وَأَحْسَنُ مَقِيلاً ﴾
(The dwellers of Paradise will, on that Day, have the best abode, and have the fairest of places for repose.)
﴿وَيَوْمَ تَشَقَّقُ السَّمَآءُ بِالْغَمَـمِ وَنُزِّلَ الْمَلَـئِكَةُ تَنزِيلاً - الْمُلْكُ يَوْمَئِذٍ الْحَقُّ لِلرَّحْمَـنِ وَكَانَ يَوْماً عَلَى الْكَـفِرِينَ عَسِيراً - وَيَوْمَ يَعَضُّ الظَّـلِمُ عَلَى يَدَيْهِ يَقُولُ يلَيْتَنِى اتَّخَذْتُ مَعَ الرَّسُولِ سَبِيلاً - يوَيْلَتَا لَيْتَنِى لَمْ أَتَّخِذْ فُلاَناً خَلِيلاً - لَّقَدْ أَضَلَّنِى عَنِ الذِّكْرِ بَعْدَ إِذْ جَآءَنِى وَكَانَ الشَّيْطَـنُ لِلإِنْسَـنِ خَذُولاً ﴾
(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.) (26. The sovereignty on that Day will be the true (sovereignty) of the Most Gracious, and it will be a hard Day for the disbelievers.) (27. And (remember) the Day when the wrongdoer will bite at his hands, he will say: "Oh! Would that I had taken a path with the Messenger.'') (28. "Ah! Woe to me! Would that I had never taken so-and-so as an intimate friend!'') (29. "He indeed led me astray from the Reminder after it had come to me. And Shaytan is to man ever a deserter.'')
