in Edition Clear Qur'an by Talal Itani / Al-A'raaf (The Heights)

7:100Is it not guidance for those who inherit the land after its inhabitants, that if We willed, We could strike them for their sins? And seal up their hearts, so that they would not hear?

7:101These towns—We narrate to you some of their tales. Their messengers came to them with the clear signs, but they would not believe in what they had rejected previously. Thus God seals the hearts of the disbelievers.
