Analyzing and investigating the narratives of certain signs of appearance and applicability in them

Bada is the emergence and change of that which has been appreciated based on the factors of God's conditional judgment. The problem of the research is the analysis of the narratives of the sure signs of the emergence of Imam Zaman (AS) and the occurrence of evil in them, which was done in a descriptive-analytical way. In many hadiths, certain and non-certain signs of the appearance of Hazrat Hojjat (AS) have been mentioned. Asemani's cry, Sufyan's exodus, Yamani's exodus, Zakia's suicide and Khasf Bida's are mentioned. The findings of the research show that according to the examination of the documents and implications of the existing traditions regarding the certainty of signs of emergence, it is possible that there is a dispute regarding the weakness of documentation and the incompleteness of their implications and the division of signs into certain and non-certain, and the relationship between the traditions claiming its certainty and the time of appearance. The sub-question of the river; Therefore, it is possible to raise the possibility that from the existing narrations about the certainty of the signs of emergence, the necessity of the fulfillment of these signs by God could not be found, and since things are inevitable by God's will, there is a possibility of bada, as a result, by ignoring the commitment to Non-occurrence of Bada in the principle of the occurrence of certain signs, we can refer to the possibility of Bada in some details and its characteristics.
