in Edition Clear Qur'an by Talal Itani / An-Naml (The Ant)

27:25If only they would worship God, who brings to light the mysteries of the heavens and the earth, and knows what you conceal and what you reveal.

27:60Or, who created the heavens and the earth, and rains down water from the sky for you? With it We produce gardens full of beauty, whose trees you could not have produced. Is there another god with God? But they are a people who equate.

27:65Say, “No one in the heavens or on earth knows the future except God; and they do not perceive when they will be resurrected.”

27:75There is no mystery in the heaven and the earth, but it is in a Clear Book.

27:87On the Day when the Trumpet is blown, everyone in the heavens and the earth will be horrified, except whomever God wills; and everyone will come before Him in humility.
