The Quran is the central religious text of Islam, which Muslims believe to be the verbatim word of God. It is widely regarded as the finest piece of literature in the Arabic language.Muslims believe the Quran to be verbally revealed through angel Gabriel of Moses, the Zabur (Tehillim or Psalms) of David, and the Injil (Gospels) of Jesus. The Quran assumes familiarity with major narratives recounted in Jewish and Christian scriptures, summarizing some, dwelling at length on others and in some cases presenting alternative accounts and interpretations of events. The Quran describes itself as a book of guidance, sometimes offering detailed accounts of specific historical events, and often emphasizing the moral significance of an event over its narrative sequence. The Quran is used along with the hadith to interpret Sharia. During prayers, the Quran is only recited in Arabic. Verse 15:9 states that God will personally protect the Quran from corruption.
