The maqta (Urdu: مقطع) is the last sher (couplet) of a ghazal, a collection of Urdu poems, in which the poet's takhallus, or pen name, is employed, often in very creative ways.
Meer in neem baaz aankhon mein
Saari masti sharaab ki see hai
(Poet : Meer Taqi Meer)
Kaba kis munh se jaaoge Ghalib
sharm tum ko magar nahiN aati.
(Mirza Ghalib)
Aaiye in se miliye yahi 'Noor haiN'
jin ke haathoN meN toota diya bhi naheeN
('Noor' Indori)
Main Josh naheeN hooN ki teri dhaoNs meiN aaooN
Naadaan! Mera naam hai Shabbeer Hasan KhaN
(Poet : Josh maleehabaadi)
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 nome de plume and the word firaq:
Tu yeh na samajh ke Firaq teri Firaq mein hai
Firaq uski Firaq mein hai jo teri Firaq mein hai
Don't think that Firaq pines for you (as in a desire to meet you)
Firaq pines for the one who pines for you (as Firaq wants to meet him first, who wants to meet you)
