(51:20) In the earth are signs for those who are certain.
(41:53) We will show them Our signs in the horizons, and within themselves, until it becomes clear to them that this is the truth. Is it not enough that your Lord is witness over all things?
(45:3-4) Surely, in the universes and the earth are signs for those who acknowledge. In your creation, and creatures that He disperses, are signs for people who are certain.
