"And among the accidents of love is the violent anxiety and silencing intensity of feeling which overcome the lover when he sees the beloved avoiding him and eschewing him; and the sign of that is sighing, and lack of vivacity, and sobbing, and having deep sighs: and on that subject I have made a poem, from which I quote:

The beautiful patience is imprisoned,
And tears are bursting forth from the eyes! "

[Tawq Al-Hamamah - Ring of the Dove by Ibn Hazm]
