Here is what the Quran says,
“Do you not see that Allah sends down rain from the sky, and We produce thereby fruits of varying colors? And in the mountains are tracts, white and red of varying shades and (some) extremely black” (Surah Fatir verse 27)
“Soon we will show them Our signs in the regions (of the earth) and in their own souls until it becomes manifest to them that this (Quran) is the Truth. Is it not enough that thy Lord doth witness all things?” (Surah Fusshilat verse 53)
