in Edition Clear Qur'an by Talal Itani / Al-An'aam (The Cattle)

6:1Praise be to God, Who created the heavens and the earth, and made the darkness and the light. Yet those who disbelieve ascribe equals to their Lord.

6:44Then, when they disregarded what they were reminded of, We opened for them the gates of all things. Until, when they delighted in what they were given, We seized them suddenly; and at once, they were in despair.

6:91They do not value God as He should be valued, when they say, “God did not reveal anything to any human being.” Say, “Who revealed the Scripture which Moses brought—a light and guidance for humanity?” You put it on scrolls, displaying them, yet concealing much. And you were taught what you did not know—neither you, nor your ancestors. Say, “God;” then leave them toying away in their speculation.

6:122Is he who was dead, then We gave him life, and made for him a light by which he walks among the people, like he who is in total darkness, and cannot get out of it? Thus the doings of disbelievers are made to appear good to them.
