Being that they are extremely humble and bashful people...
Being that they are extremely humble and bashful people, is it expected that they should stand among the people and say to them, “We are Mutaharoon and Ma’sumeen!” Furthermore, if it was not for the revelation of Ayat Al Tat-heer, do you think that Rasulullah (SA) or Ameer Al-Mu’mineen (AS) would say to the people, “Allah (SWT) has kept the "rejs" ( رجز , sin) away from us and have purified us an absolute and complete purification!” Absolutely not!
Their asceticism, bashfulness, and modesty will have prevented them from saying that. That's why Allah (SWT) carried out that mission for them and on their behalf. So, how is it that we want or expect them to behave in that manner and tell us what is clear and bright as the sun…a reality that we are able to see without them even acknowledging or insinuating it to us?!! Third : Did not Allah (SWT) reveal Ayat Al Tat-heer which all its verbs are in the present tense and indicates the continuity?
[ Yudh-hib ( يُذهب , keep away) & Wa Yutahir , ويُطَهِر purify)] And if this continuity of purification became certain, ‘Ismah would also have to be present, as we explained in the first research question. Therefore, without any doubt or debate, the verse of purification also indicates the presence of ‘Ismah. After the words of Allah (SWT), is there any need for more proofs or talk as He is the Most Wise?
We are satisfied with this explanation and there is not need for us to present the numerous traditions narrated by Rasulullah (SA) and the Imams (AS) which indicates and points to their purification and protection. History itself and their personal autobiographies are enough to stand as witnesses and proofs to that. Thus, since Ahlul-Bayt (AS) are purified and protected, is there any doubt left regarding the purification and protection of the Prophets and Messengers?
And did we read or take a look at the Message and Book of every Prophet and Messenger that previously came, such that we can confidently say that the Message and divine books lack any clear statement or verse which indicates Tat-heer and ‘Ismah of every Prophet and Messenger? Do we not find many verses in the Holy Qur’an that describe the Prophet and Messengers in such a way that makes us understand and believe in their purification and protection by Allah (SWT)?
Otherwise, what are the implications of verses such as: “Verily, he was true to what he promised [19:54]”. “Verily, he was a man of truth, a Prophet [19:41]”. “How excellent a slave!
