﴿ إِنَّ فِى خَلْقِ ٱلسَّمَٰوَٰتِ وَٱلْأَرْضِ وَٱخْتِلَٰفِ ٱلَّيْلِ وَٱلنَّهَارِ وَٱلْفُلْكِ ٱلَّتِى تَجْرِى فِى ٱلْبَحْرِ بِمَا يَنفَعُ ٱلنَّاسَ وَمَآ أَنزَلَ ٱللَّهُ مِنَ ٱلسَّمَآءِ مِن مَّآءٍۢ فَأَحْيَا بِهِ ٱلْأَرْضَ بَعْدَ مَوْتِهَا وَبَثَّ فِيهَا مِن كُلِّ دَآبَّةٍۢ وَتَصْرِيفِ ٱلرِّيَٰحِ وَٱلسَّحَابِ ٱلْمُسَخَّرِ بَيْنَ ٱلسَّمَآءِ وَٱلْأَرْضِ لَءَايَٰتٍۢ لِّقَوْمٍۢ يَعْقِلُونَ ﴾

“Verily, in the creation of the heavens and of the earth, and the succession of night and day: and in the ships that speed through the sea with what is useful to man: and in the waters which God sends down from the sky, giving life thereby to the earth after it had, been lifeless, and causing all manner of living creatures to multiply thereon: and in the change of the winds, and the clouds that run their appointed courses between sky and earth: [in all this] there are messages indeed for people who use their reason.”

They then asked for a sign to prove this and the following was revealed Surely in the creation of the heavens and the earth and the marvels contained in them and the alternation of the night and day passing and returning increasing and diminishing and the ships that run in the sea and do not become cracked and sink with what profits men of trade and merchandise and the water the rain God sends down from the heaven with which He revives the earth with vegetation after it is dead after it has dried out and He scatters abroad in it all manner of crawling thing by dividing them and spreading them throughout on account of the vegetation for they thrive on the fertile pastures it produces; and the disposition of the winds changing it from south to north from cold to warm and the clouds compelled subjugated by God’s command moving to wherever God wishes between heaven and the earth without being attached to either of the two — surely there are signs indicating His Oneness exalted be He for a people who comprehend a people who contemplate.
