The Kingdom of Saudi Arabia is keen to achieve justice in its purest form, it is always working to modernize its judicial systems, whether at the level of the general judiciary or the administrative judiciary; therefore, the Saudi administrative judiciary has been organized to achieve judicial justice in structure and jurisdiction, which is the subject of this book.

The book Al-Wasit in the Saudi Criminal System is authored by Dr. Kamal Muhammad Awwad, and in this book he took a new approach, which was represented in several points, namely: First, he based the book on the Book, the Sunnah, and the people of knowledge, and secondly, he relied on the differentiation of the three elements of crime, namely: Third, he focused on the criminal aspect of crimes, namely the existence or non-existence of a crime, and fourth, he supported the legal judgment with rulings issued by Algerian courts.

Al-Wasit in explaining the labor and social insurance systems in the Kingdom of Saudi Arabia is one of the most popular books written by Dr. Al-Sayed Eid Nayel.

The book discusses the beginning of the emergence of criminology, as it is not a modern science, but rather it is ancient, as Al-Farabi presented a research on criminology, so it is a scientific heritage, and therefore it is necessary to present many researches and works on criminology, and this is what Dr. Mohamed Nasr Mohamed presents to us in his book.
