In Section 17 of Jami's Subhat al-Abrar (within the Haft Awrang), Jami tells a tale honoring Saadi Shirazi, the 'nightingale of Shiraz.' When Saadi, praising God at dawn, strung together a celebrated couplet declaring that the green leaves of trees are, in the eye of the wise, each a book unveiling the knowledge of the Creator, a wakeful, discerning mystic saw in a dream the gates of heaven opening as ranks of angels descended, each bearing a tray of light. Trembling between fear and hope, he asked their purpose, and they answered that they carried these gifts to honor Saadi for the verse he had pierced like a pearl at dawn. The allegory teaches that reading the natural world as a scripture of divine signs is itself an act of worship, and it frames the poet's praise of God as a spiritually meritorious deed worthy of celestial reward.
