What are they asking about?

The momentous announcement

about which they differ.

They will find out.

In the end they will find out.

عَمَّ يَتَسَآءَلُونَ

عَنِ ٱلنَّبَإِ ٱلْعَظِيمِ

ٱلَّذِي هُمْ فِيهِ مُخْتَلِفُونَ

كَلَّا سَيَعْلَمُونَ

ثُمَّ كَلَّا سَيَعْلَمُونَ

Did We not make the earth smooth,

and make the mountains to keep it stable?

Did We not create you in pairs,

give you sleep for rest,

the night as a cover,

and the day for your livelihood?

Did We not build seven strong [heavens] above you,

and make a blazing lamp?

Did We not send water pouring down from the clouds

to bring forth with it grain, plants,

and luxuriant gardens?

أَلَمْ نَجْعَلِ ٱلْأَرْضَ مِهَٰدࣰا

وَٱلْجِبَالَ أَوْتَادࣰا

وَخَلَقْنَٰكُمْ أَزْوَٰجࣰا

وَجَعَلْنَا نَوْمَكُمْ سُبَاتࣰا

وَجَعَلْنَا ٱلَّيْلَ لِبَاسࣰا

وَجَعَلْنَا ٱلنَّهَارَ مَعَاشࣰا

وَبَنَيْنَا فَوْقَكُمْ سَبْعࣰا شِدَادࣰا

وَجَعَلْنَا سِرَاجࣰا وَهَّاجࣰا

وَأَنزَلْنَا مِنَ ٱلْمُعْصِرَٰتِ مَآءࣰ ثَجَّاجࣰا

لِّنُخْرِجَ بِهِۦ حَبࣰّا وَنَبَاتࣰا

وَجَنَّٰتٍ أَلْفَافًا
