Critics of Wahhabism have written numerous texts criticizing the fallacies of the Wahhabis and have been able to criticize and refute them correctly. Certainly, the beginning and basis of all these works is to find fallacies in the works of the Wahhabis, but the problem is that in most (or all) of the criticisms, the method of finding fallacies has not been explained so that others can follow the same method and find fallacies and not fall into their trap. This article seeks to present this neglected matter, namely the method of finding fallacies. To achieve this goal, a three-stage method was proposed, and at each stage, the method was applied with evidence from the book of Qaffari. The steps mentioned are: 1. Separating materials suspected of being fallacies 2. Separating materials of the position of explanation from among the suspicious materials 3. Testing the conformity of the suspicious text to the definition of each fallacy. The result of this work was to present a simple method for finding fallacies of the position of explanation in Wahhabi texts. Given that such an approach to fallacies has not been observed elsewhere, it must be said that this work is a new chapter in the criticism of Wahhabi texts.
