Nihayatul Alam — often transliterated as Nihāyatu-l-ʿĀlam — is a title used for works in classical Islamic literature and related fields (theology, tafsīr, hadith commentary, Sufi treatises, or historical chronicles). When preparing a reference for a specific PDF, the exact citation depends on the work’s author, language, publication details, and whether the PDF is a scanned historical manuscript or a modern digital edition. Below are concise, practical reference formats and examples to help you cite a Nihayatul Alam PDF in common styles (APA, MLA, Chicago), plus guidance for uncertain or partial information.
