The paper studies "the Quranic definitions". Definitions are of great significance in all various sciences, therefore, scientists have singled out particular writings.
Logicians have paid a great attention to the Quranic definitions. They divided them into four sections: al0Had at-Tam (the perfect characteristics
of the definition) and al-Had an-Naqis (the imperfect characteristics of the definition), on the one handm and, ar-Rasm at-Tam (the perfect effects of
the characteristics) and ar-Rasm an-Naqis (the imperfect effects of the characteristics), on the other hand. They set up many conditions for the definition, the most important of which is that it should be exhaustively unattainable for.
Therefore, the importance of the Quranic definitions and its characteristics have been examined and discussed.
