«ثَلَاثَةٌ تُشْرِقُ الدُّنْيَا بِبَهْجَتِهَا»
Three bring radiance to the world through their splendour.
«شَمْسُ الضُّحَى وَأَبُو إِسْحَاقَ وَالْقَمَرُ»
The morning sun, Abū Isḥāq, and the moon.
The poet joins the sun and moon with Abū Isḥāq by evoking brightness and distinction. They do not belong to a single external natural kind, but poetic comparison brings them together.
A rhetorical relation can depend on figurative resemblance and mental evocation, rather than a common material classification.
