مَرِضَ زَيْدٌ. أَضْنَاهُ السَّهَرُ.
Zayd fell ill. Sleeplessness exhausted him.
The first clause naturally suggests: «مَا سَبَبُ مَرَضِهِ؟»—what caused his illness? The second provides a contextual answer. This is a possible case of explanatory resumption (istiʾnāf bayānī): the separation reflects an implied question-and-answer relation, not substitution or mere repetition.
The implied question must be genuinely invited by the context; it cannot be arbitrarily invented after every statement.
