Who used the word NATION for Muslims for the first time?

The term "nation" in the context of Muslims was notably popularized by the Indian Muslim philosopher and politician Allama Iqbal in the early 20th century. He emphasized the idea of a distinct Muslim identity and nationhood, particularly in the context of the struggle for independence from British colonial rule in India. Iqbal's vision laid the groundwork for the later political movement that led to the creation of Pakistan in 1947.
