24:17God cautions you never to return to the like of it, if you are believers.

24:35God is the Light of the heavens and the earth. The allegory of His light is that of a pillar on which is a lamp. The lamp is within a glass. The glass is like a brilliant planet, fueled by a blessed tree, an olive tree, neither eastern nor western. Its oil would almost illuminate, even if no fire has touched it. Light upon Light. God guides to His light whomever He wills. God thus cites the parables for the people. God is cognizant of everything.

24:39As for those who disbelieve, their works are like a mirage in a desert. The thirsty assumes it is to be water. Until, when he has reached it, he finds it to be nothing, but there he finds God, Who settles his account in full. God is swift in reckoning.

24:40Or like utter darkness in a vast ocean, covered by waves, above which are waves, above which is fog. Darkness upon darkness. If he brings out his hand, he will hardly see it. He to whom God has not granted a light has no light.
