in Edition Clear Qur'an by Talal Itani / Fussilat (Explained in detail)

41:9Say, “Do you reject the One who created the earth in two days? And you attribute equals to Him? That is the Lord of the Universe.”

41:10He placed stabilizers over it; and blessed it; and planned its provisions in four days, equally to the seekers.

41:12So He completed them as seven universes in two days, and He assigned to each universe its laws. And We decorated the lower universe with lamps, and for protection. That is the design of the Almighty, the All-Knowing.

41:16So We unleashed upon them a screaming wind, for a few miserable days, to make them taste the punishment of shame in this life; but the punishment of the Hereafter is more shameful; and they will not be saved.
