Hafez's poem is the guardian of a 'secret,' a secret that implies closed speech, yet simultaneously conveys openness. It embodies both totality and dispersion, presenting a complexity that is also inherently simple, comprehensible to anyone who reads it. Often, Hafez's poetry communicates something beyond its literal meaning, creating a contradiction in both expression and poetic attitude, which is interpreted as irony in this book. Here, irony serves not only as a rhetorical device but also as a conceptual framework for understanding Hafez's poetry, considering its literary and theoretical implications. The aim of this analysis is to explore the historical necessity that led to this rhetorical (ironic) aspect in Hafez's poetic discourse.
