Muslims consider the Quran, the holy book of Islam, as the word of God and a miracle. According to Islamic tradition, the Quran was revealed miraculously to Muhammad by Allah (God) through angel, Jibrīl (Gabriel), as a perfect, verbatim copy of what was written in heaven and that had existed there for all of eternity.
The Quran describes Muhammad as "ummi", which is traditionally interpreted as "illiterate," but the meaning is rather more complex. The medieval commentators such as Al-Tabari maintained that the term induced two meanings: first, the inability to read or write in general; second, the inexperience or ignorance of the previous books or scriptures (but they gave priority to the first meaning). Besides, Muhammad's illiteracy was taken as a sign of the genuineness of his prophethood. For example, according to Fakhr al-Din al-Razi, if Muhammad had mastered writing and reading he possibly would have been suspected of having studied the books of the ancestors. Some scholars such as Watt prefer the second meaning. The suggestion is that since Muhammad had no previous knowledge of the content in the Quran, it was in fact composed of miracles. Some Muslims believe that the Quran is "a miracle of eloquence", rather than a source of scientific revelation, and consider scientific miracles as illusions from devils. However, the majority of modern Muslim thinkers accept the miracles found in the Quran and their compatibility with science. But, there still exists disagreement regarding the alleged miracles of the saints.
The definition of a miracle is "a marvellous event not ascribable to human power or the operation of any natural force and therefore attributed to supernatural, esp. divine, agency; esp. an act (e.g. of healing) showing control over nature and used as evidence that the agent is either divine or divinely favoured."
The commonly claimed miracles of the Quran can be classified into three categories: inimitability, scientific miracles, and prophecies.quran and miracles of science.quran miracles youtube
