An Epistemological Study of the Verse Tathir

The verse Tathir is regarded as one of the central verses in proving the infallibility of the Prophet and his future generation`s properties that have long been debated among the Fariqain commentators. The Sunni commentators, without any reasonable proof and only based on the context and etymology of the word al-bait, the house, have viewed all members of Quraysh in the Prophet's House, and in some cases, the Bani Hashim as included in His household. The present study examines the content of the holy verse and the disambiguation of its parts by other relative verses and relying on the explicit context and existing proofs, criticizing the scholars and proving the inconsistency of their interpretations with other Qur'anic verses, has proved the infallibility of the particular pure lights. The study has resulted in the fact the verse 33 of Ahzab, without any harmony with the discussions included in the verses before and after it and, therefore, should be regarded in itself.
