Meaning
The hoopoe as guide-bird, associated with Solomon and the quest.
How Iqbal uses it
The hudhud, Solomon's messenger-bird and the guide of the birds' pilgrimage in the Sufi tradition, is the emblem of the knowing leader who shows the way to the spiritual goal; Iqbal invokes the hoopoe as the guide every questing soul and community needs.
