فَكَيْفَ تَتَّقُونَ إِنْ كَفَرْتُمْ يَوْمًا يَجْعَلُ الْوِلْدَانَ شِيبًا
How, if you disbelieve, will you guard yourselves against a day that will turn children grey-haired? (Al-Muzzammil 73:17)
The predicate “makes” is attributed to “a day.” The day is the time or setting of overwhelming terror, not an independent acting person. The attribution intensifies the sense of dread.
The image of children turning grey conveys extraordinary severity. The specific rational-figurative feature is ascribing the action to the day, rather than merely labeling all the words metaphorical.
