The infallibility of non-prophets and imams in the Qur’an Hazrat Zahra for example

This study  has aimed to prove the chastity  of non-prophets and Imams such as the chastity of Fatima Zahra  according to  the Holy Quran.  Descriptive analytical  method was used.  We prove it by Quran verses  indicating  the  chastity  and by  hadiths.  Despite her short life, Fatima Zahra had a great status   in the history of Muslims. In terms of the concept of chastity , the origin of the word about it, and its relation with the humanity of prophets, divine grace, predestination and human free will, there are many aspects. The chastity of prophets and messengers and imams of Shiites were  mentioned, and there is no doubt that research on the issue of chastity  is one of the most important topics in Islamic thought, although due to its accuracy and complexity, many researchers don’t dig. Our prior scholars had investigated  its aspects in the books of theology  and factions  and commentaries , and focused  on the chastity of the prophets and negation of doubts surrounding it; because people had to follow them, the purity of the prophets was considered more. This  study  consisted  of  three chapters along with the conclusion and a list of sources and references adopted . In the first chapter, there are generalities and concepts, and it is divided into two parts, the first part of generalities, which includes the statement of the subject, the aim of the study, the main question, sub-questions, main hypotheses, sub-hypotheses, previous researches, the importance of the research and methodology. The second part deals with concepts and definitions in vocabulary and terms of the chastity of prophets, imams and Fatima Zahra. The second chapter is entitled chastity of non-prophets and imams. This chapter  was divided into five parts, each part included several topics. The first topic is  chastity in Shia and Sunni, and the second topic is  the necessity of chastity of the prophets, and the third topic is  the necessity of chastity  of Imamate, and the fourth topic is the chastity of angels, and the fifth topic is the chastity of non-prophets and non-imams in the Qur’an. Also its topics include several topics and sub-topics. The third chapter is entitled Fatima Zahra (PBUH) and her chastity in the Qur’an and hadiths. The first topic is the chastity of Fatima Zahra (PBUH) in the verses of the Qur’an. The second topic is Fatima Zahra’s innocence in hadiths. During this study, we reached several conclusions including: 1- Mrs. Fatima Zahra  was certified for her chastity and modesty 2- She is a model for women in Islam 3- she was exposed to many crises in her life.
