Naseem Hijazi bases most of his work in Islamic history. In dealing with this history, he shows both the rise and fall of the Islamic Empire. His novels Muhammad Bin Qasim, Aakhri Ma'raka, Qaisar-o Kisra and Qafla-i Hijaz describe the era of Islam's rise to political, militaristic, economic, and educational power. While Yusuf Bin Tashfain, Shaheen, Kaleesa aur Aag, and Andheri Raat ke Musafir describe the period of Spanish Reconquista. In one of these novels (Kaleesa Aur Aag) he has painfully, yet truthfully, depicted the infamous Spanish Inquisition that began by targeting the Spanish Jews and ended also with the conversion or expulsion of the Moriscos or crypto-Muslims outwardly converted to Christianity.
