The Thunder
الٓمٓر ۚ تِلْكَ ءَايَـٰتُ ٱلْكِتَـٰبِ ۗ وَٱلَّذِىٓ أُنزِلَ إِلَيْكَ مِن رَّبِّكَ ٱلْحَقُّ وَلَـٰكِنَّ أَكْثَرَ ٱلنَّاسِ لَا يُؤْمِنُونَ
Alif, Lam, Meem, Ra. These are the verses of the Book; and what has been revealed to you from your Lord is the truth, but most of the people do not believe.

ٱللَّهُ ٱلَّذِى رَفَعَ ٱلسَّمَـٰوَٰتِ بِغَيْرِ عَمَدٍ تَرَوْنَهَا ۖ ثُمَّ ٱسْتَوَىٰ عَلَى ٱلْعَرْشِ ۖ وَسَخَّرَ ٱلشَّمْسَ وَٱلْقَمَرَ ۖ كُلٌّ يَجْرِى لِأَجَلٍ مُّسَمًّى ۚ يُدَبِّرُ ٱلْأَمْرَ يُفَصِّلُ ٱلْـَٔايَـٰتِ لَعَلَّكُم بِلِقَآءِ رَبِّكُمْ تُوقِنُونَ
It is Allah who erected the heavens without pillars that you [can] see; then He established Himself above the Throne and made subject the sun and the moon, each running [its course] for a specified term. He arranges [each] matter; He details the signs that you may, of the meeting with your Lord, be certain.
وَهُوَ ٱلَّذِى مَدَّ ٱلْأَرْضَ وَجَعَلَ فِيهَا رَوَٰسِىَ وَأَنْهَـٰرًا ۖ وَمِن كُلِّ ٱلثَّمَرَٰتِ جَعَلَ فِيهَا زَوْجَيْنِ ٱثْنَيْنِ ۖ يُغْشِى ٱلَّيْلَ ٱلنَّهَارَ ۚ إِنَّ فِى ذَٰلِكَ لَـَٔايَـٰتٍ لِّقَوْمٍ يَتَفَكَّرُونَ
And it is He who spread the earth and placed therein firmly set mountains and rivers; and from all of the fruits He made therein two mates; He causes the night to cover the day. Indeed in that are signs for a people who give thought.
