The book Fundamentals of Islamic Education to the lost childhood in this age, the reader may wonder why the author chose this title to present his book, although it is famous for the twentieth century as the age of light and science, and that the human sciences, including education, have received a great deal of attention from scientists and philosophers of education! The loss often arises from exaggerated concern, and this is what actually happened, as the exaggeration of most modern educational philosophers and founders in caring for childhood led to its extension as a stage of human development, so the young person stayed behind its borders for a period of time that does not exceed it.

Imam Al-Dhahabi's book - A Thematic, Analytical, and Educational Study is the third installment in the series of Flags of Education in the History of Islam, which deals with the educational views of Imam Al-Dhahabi and his educational criticism based on fixed criteria such as demanding sincerity, avoiding hypocrisy, and elevating science from gaining knowledge and seeking prestige and money.
