Certain Qur’anic expressions attribute effects to closely associated causes or circumstances. Such attributions must be interpreted from meaning and context rather than from an isolated word.
وَإِذَا تُلِيَتْ عَلَيْهِمْ آيَاتُهُ زَادَتْهُمْ إِيمَانًا
When His verses are recited to them, they increase them in faith. (al-Anfāl 8:2)
يَوْمًا يَجْعَلُ الْوِلْدَانَ شِيبًا
A day that will turn children gray-haired. (al-Muzzammil 73:17)
The first connects recitation with an increase in faith; the second attributes a terrifying effect to the day itself. Context and the relationship between an action and its cause or circumstance determine the rhetorical analysis.
