Tawjīh permits two distinct interpretations of an expression. Tajāhul al-ʿārif is an apparently uninformed question or declaration by one who knows, serving a rhetorical purpose. Qawl bi-l-mūjib accepts the interlocutor’s words while turning their implication toward an unintended conclusion.
وَمَا تِلْكَ بِيَمِينِكَ يَا مُوسَى
What is that in your right hand, O Moses?
The question should be analyzed in its narrative setting rather than treated as an ordinary request for information; the rhetorical occasion alters what the interrogative achieves.
