According to search-discovered classical Islamic scholarship, the term Suhuf (الصحف), meaning 'Pages' or 'Scrolls', refers to the divine revelations sent down by Allah to prophets preceding the revelation of the major scriptures. Linguistically analyzed by scholars like Al-Tabari, the word's root denotes something spread out to be written upon. The Quran makes specific reference to the 'Suhuf of Ibrahim and Musa' (Quran 87:19), highlighting them as foundational scriptures that contained the core, timeless message of monotheism (Tawhid) and righteousness. Tafsir experts like Ibn Kathir explain that the mention of these earlier revelations serves to affirm the Quran's authenticity, demonstrating that its message is not new but a continuation and culmination of the same divine guidance sent to all prophets. While a distinction is often made between the Suhuf (smaller collections of pages) and a Kitab (a complete book like the Torah or Quran), belief in their divine origin is an essential part of Islamic faith, underscoring the unity of the prophetic mission throughout history.
