How Iqbal uses it
Bayaan is expression or eloquent statement, the power to set forth a meaning clearly and movingly. Iqbal values bayaan that clarifies and persuades in the service of truth, and the Quranic resonance of the word lends it gravity. Eloquence, for him, is a trust to be spent on what matters.
