Ḥusn al-taʿlīl supplies an artistically fitting, imagined explanation for an occurrence or property, rather than simply reporting its normal cause. Al-madhhab al-kalāmī organizes a claim through explicit reasoning so that the argumentative relationship becomes salient to the listener.
لَوْ كَانَ فِيهِمَا آلِهَةٌ إِلَّا اللَّهُ لَفَسَدَتَا
If there had been deities besides Allah in the heavens and earth, both would have fallen into disorder.
This conditional reasoning exemplifies argumentation, not a poetic invention of causation. The shared presence of words such as “reason” or “cause” does not make the two devices identical.
