The plants are the origin of coal
 

And who brings forth herbage (4) Then makes it dried up , dust-colored (5
Surah: The most high
This verse refers to a period of time of earth life in which the herbage covered it, then it had been compressed under the ground and turned into a huge tons of black coal , whereas the plants are the origin of coal because when they die, they decay and remain the carbon only from it
The modern science emphasized this idea while it was mentioned in the holy Qur'an ( the miracle of our prophet Mohammed )since the date of being a messenger of God
