Thanks be to (Allah), The God of all mankind and Peace and Prayers upon the Prophet Mohammed. After completing my research by help of Allah, I mentioned the terms of performance, requisition and repetition. These terms are different from the point of view the Fundamentalists. That they are one of the parts of the positive order or subordinate to it? But we can't say that they aren't parts of the positive order and time is the main effective element on these terms because the time is the cause of performance and without time is the cause of requisition and the defect in worship is the cause of repetition and the cause is a kind of positive order which the fundamentalists had agreed on it. These three terms have an important fundamentals issue and these issues I mentioned in my research.
