The philology of "Ahl", and its study "Tathir" Verse: an analysis in Shia and Suni interpretations

"Tathir" Verse is one of the most controversial verses about the Ismat (chastity) of Ahlolbayt in Shia and Sonny religious circles. Shia know the Khamse tayyebah specially as ahlolbayt, and in oppose, some of the Suni religious scientists know the prophet's wives specially as ahlolbayt, and some others know the prophet's wives and the Khamse Tayyebah as ahlolbyt, and some others know the relatives as ahlolbayt.In this field, one of the commentator's reasons for this claim is the change of preposition from the "Plural – female" to "Plural – male" in the “Tathir” Verse. This research has explored the term "Ahl" and its usages of in Quran, and has proved that ahlolbayt is only interpreted as Khamse Tayyebah with a descriptive – analysis approach.
