27:1Ta, Seen. These are the Signs of the Quran—a book that makes things clear.

27:40He who had knowledge from the Book said, “I will bring it to you before your glance returns to you.” And when he saw it settled before him, he said, “This is from the grace of my Lord, to test me, whether I am grateful or ungrateful. He who is grateful, his gratitude is to his own credit; but he who is ungrateful—my Lord is Independent and Generous.”

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