Document Evaluation of Causes for Revelation of Chapter Dahr concerning Ahl al-Bayt

One of the issues discussed by the knowledge of causes for revelation is the existence of discrepancy concerning some chapters of the holy Quran. Chapter Hal Ataa is of the most important chapters in this regard which demands a critical and correct judgment. The author first studies the sources and evaluates the documents of some hadiths concerning the causes for revelation of this chapter and then tries to prove that revelation of this chapter in honor of Ahl al-Bayt [as some people like Ibn Jowzi and Ahmad Amin claim] is not a fictitious story made by some Shi`te but a reality which its document reliability is demonstrable based on general principles of hadith scholarship.
