The fundamental rule of washing the hands of the one who is awake from his sleep at the start of ablution, which is mentioned in the book “Oyoun Al-Evidence and Issues of Controversy among the Jurists of Al-Amsar”by Ibn Al-Qassar

The research deals with the issue of hand washing for those who wanted to perform ablution for those who woke up from their sleep, to clarify the fundamental crippling of them specifically. One of the necessities of this restriction was passing through jurisprudential issues, the evidences of the jurists, and the debates that were present between the folds of that issue. Then the conclusion is to derive a comprehensive origin from it, so the research on this simulates the Hanafi method, as it assumes that in the jurisprudential heritage and subsidiary issues unless they are reconciled, so the research adopted this task and took it upon itself, but within a specific scope, which is the book Eyes of Evidence in Matters of Dispute between the Jurists of Al-Amsar by Ibn Al-Qassar Maliki. The research sought the sample of the study to explain it in detail, then to recite it, and then finally to develop the fundamentalist rules, which were incorporated under it as a comprehensive principle that gathers its strife, and it is a model for many issues, but the search was limited to it as an example in which the article becomes clear only, and one of the necessities of the research is to define the term recitation. The fundamentalist and what is meant by it and what is intended by it, by explaining its linguistic and terminological meaning, an introduction to accessing the core of its subject, as the task of defining the terminology will be to adjust the direction of the research and direct its rudder towards its main goal, so that it does not diverge and the unity of its subject is lost between the many parts it contains.   Then it is a statement of the methodologies of the jurists and the foundations of their schools of thought that they relied on and made for themselves in order to accept evidence from the beginning or criticize it and derive rulings from it at the end, to clarify the intellectual mentality and the extent of maturity reached by the original thought, which the imams of the schools established for it, and they followed what they worshiped who came after them. their students until he reached what he has reached today, clarity, maturity and firmness.It is also not hidden from those who have knowledge of these curricula of their importance in preserving the entity of the jurisprudential schools, and then the consistency of the provisions of the glorious Sharia, and its ability to simulate reality by finding solutions to emerging contemporary issues by linking them to similar ones and returning everyone to a comprehensive origin through holistic rules.
