Maqta'

In Persian, Turkic and Urdu poetry, the maqta is the final bayt, or couplet, of a ghazal. In this sense, it is the opposite of the matla'. The poet's takhallus, or pen name, is usually employed in the maqta, often in very creative ways.
A shayar can use the maqta in a variety of interesting ways. He can "talk to himself", "to somebody else", "refer to something" etc. For example Firaq Gorakhpuri, whose takhallus is the word for the common theme in Urdu poetry of the state of pining for the beloved, plays on his pen name and the word firaq:
Urdu:
تو یہ نہ سمجھنا کے فِراق تیری فِراق میں ہیں
فِراق اُسکی فِراق میں ہہ جو تیری فِراق میں ہہ
