Tadlis has been one of the significant phenomena in the process of transmitting hadiths, and not paying attention to it will damage the validity of hadith Sanads. This phenomenon is rooted in the history of hadith and many narrators at different levels have committed it. One of the important issues in studying this phenomenon is the method of discovering it in hadith Sanads as well as recognizing the motivations of narrators to do it. In this article, based on an objective example, this important issue has been addressed; This is an example of the Unusual names that Darqotni has used to name his master Muhammad ibn 'Umar Je'abi. A case-by-case analysis of each of these names first proved that they were all in fact refer to Ji'abi; Then the unusualness of these names about Ji'abi and, as a result, Darqotni's Tadlis in mentioning him was proved. In the end, various hypotheses were expressed in Darqotni's possible motives for the Tadlis, the most important of which was his suspicion of Ji'abi at the later period of his life, which may have been pretended not to narrate much from him by changing the method of naming Jiabi.
