What is the title of the poem on the Founding Fathers of Pakistan?
The question is actually a little too vague for a single definitive answer to be provided. That said, a logical answer to the question of who wrote a poem on Pakistan's founders and what was the title of that poem would be Allama Muhammad Iqbal (1877-1938), a prominent Indian Muslim leader and poet who is considered one of the founders of modern Pakistan. Iqbal's poetry was heavily influenced by his Islamic faith and by his fervent belief in the need for a separate Muslim nation from India.
In a more contemporary vein, Muhammad Raza Master wrote a poem dedicated to Muhammad Ali Jinnah, another major figure in Pakistani history known as "Quaid-e-Azam," or "Great Leader,":
Quaid-i-Azam, the founder of nation,/ Every soul knows his great narrations,/He was the cause of Pakistan's creation . . . Quaid-i-Azzam was a true and devoted leader,/ He was the peaceful and good preacher . . ." [www.poemhunter.com/poem/quaid-e-azam-founder-of-pakistan/]
As Iqbal was the National Poet of Pakistan, he is more closely identified with poetry and Pakistani history, but given the vagueness of the question, these are two options.
