Read Ruku 377 of the Quran

وَمَا يَسْتَوِى ٱلْبَحْرَانِ هَـٰذَا عَذْبٌۭ فُرَاتٌۭ سَآئِغٌۭ شَرَابُهُۥ وَهَـٰذَا مِلْحٌ أُجَاجٌۭ ۖ وَمِن كُلٍّۢ تَأْكُلُونَ لَحْمًۭا طَرِيًّۭا وَتَسْتَخْرِجُونَ حِلْيَةًۭ تَلْبَسُونَهَا ۖ وَتَرَى ٱلْفُلْكَ فِيهِ مَوَاخِرَ لِتَبْتَغُوا۟ مِن فَضْلِهِۦ وَلَعَلَّكُمْ تَشْكُرُونَ ﴿١٢﴾

And not alike are the two bodies of water. One is fresh and sweet, palatable for drinking, and one is salty and bitter. And from each you eat tender meat and extract ornaments which you wear, and you see the ships plowing through [them] that you might seek of His bounty; and perhaps you will be grateful.

يُولِجُ ٱلَّيْلَ فِى ٱلنَّهَارِ وَيُولِجُ ٱلنَّهَارَ فِى ٱلَّيْلِ وَسَخَّرَ ٱلشَّمْسَ وَٱلْقَمَرَ كُلٌّۭ يَجْرِى لِأَجَلٍۢ مُّسَمًّۭى ۚ ذَٰلِكُمُ ٱللَّهُ رَبُّكُمْ لَهُ ٱلْمُلْكُ ۚ وَٱلَّذِينَ تَدْعُونَ مِن دُونِهِۦ مَا يَمْلِكُونَ مِن قِطْمِيرٍ ﴿١٣﴾

He causes the night to enter the day, and He causes the day to enter the night and has subjected the sun and the moon - each running [its course] for a specified term. That is Allah, your Lord; to Him belongs sovereignty. And those whom you invoke other than Him do not possess [as much as] the membrane of a date seed.

إِن تَدْعُوهُمْ لَا يَسْمَعُوا۟ دُعَآءَكُمْ وَلَوْ سَمِعُوا۟ مَا ٱسْتَجَابُوا۟ لَكُمْ ۖ وَيَوْمَ ٱلْقِيَـٰمَةِ يَكْفُرُونَ بِشِرْكِكُمْ ۚ وَلَا يُنَبِّئُكَ مِثْلُ خَبِيرٍۢ ﴿١٤﴾

If you invoke them, they do not hear your supplication; and if they heard, they would not respond to you. And on the Day of Resurrection they will deny your association. And none can inform you like [one] Acquainted [with all matters].
