Ghalib is poet, some of poetic cricles dont agree that iqbal was that much good in poetry itslef but as a matter of Subject Ghalib wasnt comitted to subject or some specific school of thought Ghalib is best for his usuage of “tarkeeb” in poetry; in world no one was so good to use this poetic sense with such accuracy.
Hur aik baat pe kehtey ho tum ke tu kia hay
tumhin kahoo ke yeh undaze guftgu kia hay
what a brilliant usuage of very commonly use phrase.
But if above sheer is considerd in light of subjec based poetry it has verly limited life.
Hur lahza hey moman ki ni shaan nai aan
a simple sheer in poetic sense but what a brilliant and long time usage of subject.Qaimat ke din tuk is haqequt se inkar maumakn nahi ke moman hone ki jo her lamha azmaish hey us ki kia khoobsurati hey.\
