3:7It is He who revealed to you the Book. Some of its verses are definitive; they are the foundation of the Book, and others are unspecific. As for those in whose hearts is deviation, they follow the unspecific part, seeking descent, and seeking to derive an interpretation. But none knows its interpretation except God and those firmly rooted in knowledge say, “We believe in it; all is from our Lord.” But none recollects except those with understanding.

3:190In the creation of the heavens and the earth, and in the alternation of night and day, are signs for people of understanding.

3:191Those who remember God while standing, and sitting, and on their sides; and they reflect upon the creation of the heavens and the earth: “Our Lord, You did not create this in vain, glory to You, so protect us from the punishment of the Fire.”
