Logical Metaphor and Its Use
There is no doubt that figurative speech is used in the Book and the Sunnah. From that, are the words of the Exalted:
"And when our verses are recited to them, they increase them in faith.'' (al-Anfāl; 2)
Linking the increase to the verses here is figurative because (in reality), they are a cause for the increase. It is Allah alone that actually increases it (the faith).
Also, the statement of the Exalted:
"A day that shall make the young grey haired." (al-Muzammil; 17)
