A Study of the Evidence of Ahlul Bayt and the Concept of " Will" in the Verse of Purification

The 33rd verse of Surah “al-Ahzab” talks about God’s will to purify the Ahlul Bayt (a.s) with extensive purification. Differences in the pronouns of part of this verse with the previous and next verses have led to different viewpoints in deciding the evidence of Ahlul Bayt and the concept of “will” in the verse of purification. The verse of purification is a key for the Quranic proof of “Ismah” (protection), hence, it seems necessary to do some major research on the issue. The purpose of this paper is to decide the concept of “will” and to know the evidence of those who reached the level of “Ismah” and purity with a will and for the purity they have gained, they can be a reliable source in scientific, religious and political issues of society. The research and study on the Islamic texts achieved its goal of deciding the evidence of Ahlul Bayt and of proving the evolutionary will in the form of Sharia (not free from or negating Sharia). Accordingly, it is proven that the Ahlul Bayt’s voluntary purification goes along with God’s definite declaration.
