6 verses have
darkness
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.

6:39Those who reject Our revelations are deaf and dumb, in total darkness. Whomever God wills, He leaves astray; and whomever He wills, He sets on a straight path.

6:59With Him are the keys of the unseen; none knows them except He. And He knows everything on land and in the sea. Not a leaf falls but He knows it; and there is not a single grain in the darkness of earth, nor is there anything wet or dry, but is in a clear record.

6:63Say, “Who delivers you from the darkness of land and sea?” You call upon Him humbly and inwardly: “If He delivers us from this, We will surely be among the thankful.”

6:97And it is He Who created the stars for you, that you may be guided by them in the darkness of land and sea. We thus explain the revelations for people who know.

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.
