It has been narrated on the authority of Imam Sadiq (P.B.U.H.) that Qom is immune to disasters and Shia are suggested to seek refuge in this city during trials (fitan), whereas we have witnessed this city has not been unaffected by damages in the time of different incidents, such as flood, earthquake and epidemics. Thus this question is raised that how these two matters should be interpreted? In this descriptive-analytical study which has been designed to answer this question, likelihood of unfamiliarity and fabrication of these narrations was denied and their contents were evaluated through analytical (fiqh al-ḥadīthī)-empirical and historical approaches. As a result, there were found that one group of traditions are temporal, so they are not questionable and non-temporal traditions are divided into three categories: protection from oppressors, celestial punishment and disaster, and evil temptations and immunization in spiritual aspect. None of these three is in contrast to other difficulties like flood, illness, etc. There is no sound narration stating generally that no disaster, problem and difficulty will occur in this city.
