Allaah (The Most High) said:

أَأَنتُمْ أَشَدُّ خَلْقًا أَمِ السَّمَاءُ ۚ بَنَاهَا

رَفَعَ سَمْكَهَا فَسَوَّاهَا

وَأَغْطَشَ لَيْلَهَا وَأَخْرَجَ ضُحَاهَا

وَالْأَرْضَ بَعْدَ ذَٰلِكَ دَحَاهَا

أَخْرَجَ مِنْهَا مَاءَهَا وَمَرْعَاهَا

وَالْجِبَالَ أَرْسَاهَ

مَتَاعًا لَّكُمْ وَلِأَنْعَامِكُمْ

فَإِذَا جَاءَتِ الطَّامَّةُ الْكُبْرَىٰ

يَوْمَ يَتَذَكَّرُ الْإِنسَانُ مَا سَعَىٰ

وَبُرِّزَتِ الْجَحِيمُ لِمَن يَرَىٰ

فَأَمَّا مَن طَغَىٰ

 وَآثَرَ الْحَيَاةَ الدُّنْيَا

فَإِنَّ الْجَحِيمَ هِيَ الْمَأْوَىٰ

وَأَمَّا مَنْ خَافَ مَقَامَ رَبِّهِ وَنَهَى النَّفْسَ عَنِ الْهَوَىٰ

فَإِنَّ الْجَنَّةَ هِيَ الْمَأْوَىٰ

يَسْأَلُونَكَ عَنِ السَّاعَةِ أَيَّانَ مُرْسَاهَا

فِيمَ أَنتَ مِن ذِكْرَاهَا

إِلَىٰ رَبِّكَ مُنتَهَاهَا

إِنَّمَا أَنتَ مُنذِرُ مَن يَخْشَاهَا

كَأَنَّهُمْ يَوْمَ يَرَوْنَهَا لَمْ يَلْبَثُوا إِلَّا عَشِيَّةً أَوْ ضُحَاهَا

Are you more difficult to create, or is the heaven that He constructed?

He raised its height, and He has equally ordered it,

Its night He covers with darkness, and its forenoon He brings out (with light).

And after that He spread the earth;

And brought forth therefrom its water and its pasture;

And the mountains He has fixed firmly;

(To be) a provision and benefit for you and your cattle.

But when there comes the greatest catastrophe (i.e. the Day of Recompense, etc.),

The Day when man shall remember what he strove for,

And Hell-fire shall be made apparent in full view for (every) one who sees,

Then, for him who Tagha (transgressed all bounds, in disbelief, oppression and evil deeds of disobedience to Allah).

And preferred the life of this world (by following his evil desires and lusts),

Verily, his abode will be Hell-fire;

But as for him who feared standing before his Lord, and restrained himself from impure evil desires, and lusts.

Verily, Paradise will be his abode.

They ask you (O Muhammad) about the Hour, – when will be its appointed time?

You have no knowledge to say anything about it,

To your Lord belongs (the knowledge of) the term thereof?

You (O Muhammad) are only a warner for those who fear it,

The Day they see it, (it will be) as if they had not tarried (in this world) except an afternoon or a morning.

[Aayaat 27-45]
