The concept of artistic unity, in Ancient Arabic criticism, is achieved through the smallest unity. This is expressed through the poetic verse, which is meaningfully and rhythmically a unit that possess its own integrity. Thus, this makes it separate from the poem. However, this separation becomes a connection when it participates with other verses to build the poem. So, we may argue that this unity creates a separation on the level of the poetic line. On the other hand, it also forges connection on the level of the poem as a whole, and its causality with its neighboring verses.
And through the numerous objects of the poem, the article "Unity" achieves by what was named Hosn AL kharoj to give a good connection to the point of assemblage of these objects.
