Luqman/31:10
He created the heavens without a pillar that you see. And He placed stabilizers on the earth that you may not be shaken, and He spread therein every kind of creature. And We rained down water from the sky, and We caused to grow therein every beautiful variety.
خَلَقَ السَّمٰوَاتِ بِغَيْرِ عَمَدٍ تَرَوْنَهَا وَاَلْقٰى فِي الْاَرْضِ رَوَاسِيَ اَنْ تَم۪يدَ بِكُمْ وَبَثَّ ف۪يهَا مِنْ كُلِّ دَٓابَّةٍۜ وَاَنْزَلْنَا مِنَ السَّمَٓاءِ مَٓاءً فَاَنْبَتْنَا ف۪يهَا مِنْ كُلِّ زَوْجٍ كَر۪يمٍ
