Verse 15

وَأَلۡقَىٰ فِي ٱلۡأَرۡضِ رَوَٰسِيَ أَن تَمِيدَ بِكُمۡ وَأَنۡهَٰرٗا وَسُبُلٗا لَّعَلَّكُمۡ تَهۡتَدُونَ ١٥
Dr. Mustafa Khattab, the Clear Quran
He has placed into the earth firm mountains, so it does not shake with you, as well as rivers, and pathways so you may find your way.
13:17 - Ar-Ra'd

Verse 17

أَنزَلَ مِنَ ٱلسَّمَآءِ مَآءٗ فَسَالَتۡ أَوۡدِيَةُۢ بِقَدَرِهَا فَٱحۡتَمَلَ ٱلسَّيۡلُ زَبَدٗا رَّابِيٗاۖ وَمِمَّا يُوقِدُونَ عَلَيۡهِ فِي ٱلنَّارِ ٱبۡتِغَآءَ حِلۡيَةٍ أَوۡ مَتَٰعٖ زَبَدٞ مِّثۡلُهُۥۚ كَذَٰلِكَ يَضۡرِبُ ٱللَّهُ ٱلۡحَقَّ وَٱلۡبَٰطِلَۚ فَأَمَّا ٱلزَّبَدُ فَيَذۡهَبُ جُفَآءٗۖ وَأَمَّا مَا يَنفَعُ ٱلنَّاسَ فَيَمۡكُثُ فِي ٱلۡأَرۡضِۚ كَذَٰلِكَ يَضۡرِبُ ٱللَّهُ ٱلۡأَمۡثَالَ ١٧
Dr. Mustafa Khattab, the Clear Quran
He sends down rain from the sky, causing the valleys to flow, each according to its capacity. The currents then carry along rising foam, similar to the slag produced from metal that people melt in the fire for ornaments or tools. This is how Allah compares truth to falsehood. The ˹worthless˺ scum is then cast away, but what benefits people remains on the earth. This is how Allah sets forth parables.
39:21 - Az-Zumar

Verse 21

أَلَمۡ تَرَ أَنَّ ٱللَّهَ أَنزَلَ مِنَ ٱلسَّمَآءِ مَآءٗ فَسَلَكَهُۥ يَنَٰبِيعَ فِي ٱلۡأَرۡضِ ثُمَّ يُخۡرِجُ بِهِۦ زَرۡعٗا مُّخۡتَلِفًا أَلۡوَٰنُهُۥ ثُمَّ يَهِيجُ فَتَرَىٰهُ مُصۡفَرّٗا ثُمَّ يَجۡعَلُهُۥ حُطَٰمًاۚ إِنَّ فِي ذَٰلِكَ لَذِكۡرَىٰ لِأُوْلِي ٱلۡأَلۡبَٰبِ ٢١
Dr. Mustafa Khattab, the Clear Quran
Do you not see that Allah sends down rain from the sky—channelling it through streams in the earth—then produces with it crops of various colours, then they dry up and you see them wither, and then He reduces them to chaff? Surely in this is a reminder for people of reason.
14:32 - Ibrahim

Verse 32

ٱللَّهُ ٱلَّذِي خَلَقَ ٱلسَّمَٰوَٰتِ وَٱلۡأَرۡضَ وَأَنزَلَ مِنَ ٱلسَّمَآءِ مَآءٗ فَأَخۡرَجَ بِهِۦ مِنَ ٱلثَّمَرَٰتِ رِزۡقٗا لَّكُمۡۖ وَسَخَّرَ لَكُمُ ٱلۡفُلۡكَ لِتَجۡرِيَ فِي ٱلۡبَحۡرِ بِأَمۡرِهِۦۖ وَسَخَّرَ لَكُمُ ٱلۡأَنۡهَٰرَ ٣٢
Dr. Mustafa Khattab, the Clear Quran
It is Allah Who created the heavens and the earth and sends down rain from the sky, causing fruits to grow as a provision for you. He has subjected the ships for your service, sailing through the sea by His command, and has subjected the rivers for you.
