Ahlulbayt in Quran and blindness to them is best explained by dark magic.

[Mystic]

The 2nd chapter of Quran goes to the heart of what occurred in the previous nation to be entrusted God's guidance.

Although Quran is revealed in a different order that it's order it took in final form, the final form is important to be read in order as well.

I posted this before:

Shakir 2:248] And the prophet said to them: Surely the sign of His kingdom is, that there shall come to you the chest in which there is tranquillity from your Lord and residue of the relics of what the children of Musa and the children of Haroun have left, the angels bearing it; most surely there is a sign in this for those who believe.
[Pickthal 2:248] And their Prophet said unto them: Lo! the token of his kingdom is that there shall come unto you the ark wherein is peace of reassurance from your Lord, and a remnant of that which the house of Moses and the house of Aaron left behind, the angels bearing it. Lo! herein shall be a token for you if (in truth) ye are believers.
[Yusufali 2:248] And (further) their Prophet said to them: "A Sign of his authority is that there shall come to you the Ark of the covenant, with (an assurance) therein of security from your Lord, and the relics left by the family of Moses and the family of Aaron, carried by angels. In this is a symbol for you if ye indeed have faith."
Some Hadiths:
والعياشي عن الصادق عليه السلام انه سئل عن قوله تعالى وبقية مما ترك آل موسى وآل هارون قال ذريّة الأنبياء.
Imam Sadiq (as) was asked about "the remain of what the family of Moses and the family of Aaron has left" -he said: the offspring of Prophets.
وفي الكافي والعياشي عن الباقر عليه السلام في هذه الآية قال ورضراض الألواح فيها العلم والحكمة.
Imam Baqir (as) regarding this verse "he place in it tablets in which it was knowledge and wisdom"
العياشي عن الرضا عليه السلام انه قال كان فيه ألواح موسى التي تكسرت والطست التي يغسل فيها قلوب الأنبياء.
From Imam Reda (as) in it was the tablets of Moses that were broken and a bowl which in it was washed the hearts of the Prophets.
والقمّي عنه قال السكينة ريح من الجنة لها وجه كوجه الإنسان وكان إذا وضع التابوت بيد يدي المسلمين والكفار فان تقدم التابوت رجل لا يرجع حتى يقتل أو يغلب ومن رجع عن التابوت كفر وقتله الإمام.
From Imam Reda (as): "The tranquility is a scent from paradise it has a image like the image of a human and when it the Ark (Tabut) was place amount the hands of the submitters and disbelievers a man would rise who want not return until he fought or was victorious and who turned back regarding the Ark (Tabut) disbelieved and fought the leader."
وفي المعاني سئل الكاظم عليه السلام ما كان تابوت موسى وكم كان سعته قال ثلاثة أذرع في ذراعين قيل وما كان فيه قال عصا موسى والسكينة قيل وما السكينة قال روح الله يتكلم كانوا إذا اختلفوا في شيء كلّمهم وأخبرهم ببيان ما يريدون.
From Imam Kadhim (as) he was asked what was the Tabut (ark) of Moses and how many relics were in it, he said three that were place amount those it was placed, it was said "and what was in it" "the staff of Moses and the tranquility" and he was asked what is the tranquility "the spirit of God that spoke when they disputed regarding a thing, he spoke to them and informed with an explanation of what they wished".
وعن الصادق عليه السلام قال إنما مثل السلاح فينا مثل التابوت في بني إسرائيل كانت بنو إسرائيل أي أهل بيت وجد التابوت على بابهم اوتوا النبوة فمن صار إليه السلاح منّا أوتي الإمامة. وفي رواية حيث ما دار التابوت في بني إسرائيل دار الملك وأينما دار السلاح فينا دار الملك والعلم.
From Sadiq (as) the likeness of the weapon among us is like the ask in the childen of Isreal the children of Israel any family that was given the ask on their door the prophethood would be given to them, so whoever us the weapon from us from us to, he is given leadership, and from another tradition, whoever was given the Ark in children of Israel were given the authority and whoever is given the weapon in us is given the authority and knowledge.
وفي أخرى سئل الكاظم عليه السلام ما السكينة فقال ريح تخرج من الجنة لها صورة كصورة الإنسان ورائحة طيبة وهي التي نزلت على إبراهيم فأقبلت تدور حول أركان البيت وهو يصنع الأساطين فقيل له هي التي قال الله تعالى فيه سكينة من ربكم وبقية مما ترك آل موسى وآل هارون قال وتلك السكنية في التابوت وكان فيه طست يغسل فيه قلوب الأنبياء وكان التابوت يدور في بني إسرائيل مع الأنبياء ثم أقبل علينا فقال ما تابوتكم قلنا السلاح قال صدقتم هو تابوتكم.
and there is many more hadiths, including one from Imam Ali (as) that says "verily God has shown you he has put the succession in the offspring of Prophets" using this verse as proof of Ahlulbayt (as), so this verse is a proof among many proofs of the position of Ahlulbayt (as) by lesson of an Ahlulbayt (as) in the past.

Now this is a verse a key verse. Most of what was iterated in that Surah was not the controversial to the Jews.

However, if you read the Torah today, you will notice, while God took a covenant with respect to Aaron and his chosen offspring,  then covenant was taken back by God and instead appointed Yushua.

And Aaron supposedly is older then Moses and died before Moses.  Since this is a dispute, Quran then seeks to clarify to the Jews, not just by telling them, but by giving them insight to the purpose of the talk of the true Kings of the offspring of Abraham, those who were the true leaders of humanity.

In fact, all the talk from Seth to family of Abraham in the Torah, was to make ground work to the covenant of Aaron and his family, which also, due to the prayer of Moses with respect "The one God will send" manifests Mohammad and his holy family as well.

Aaron is a huge topic in Quran.

Here we see it's clear that Quran clarified in the past, the sign of Authority was inherited and passed down by the family of Moses which by singular "taraka", is the family of Aaron.

And if you read the dead see scrolls there is emphasis that the covenant pertaining to Aaron's family and the exalted leadership (priesthood) was meant for only the righteous purified ones of his offspring.

This is the first instance where the word "Aul" (family) is used with respect to a Prophet, in this case, two of the founders, Moses and Aaron.


Most Muslims believe Yoshua succeeded Moses due to hadiths as well as that it was Jews believe, but Joshua name doesn't at all appear in the Quran.  Aaron appears 20 times, and 12 times a long side Moses' name.

And aside from that, has been mention more times without name.

We see that the Quran introduces the concept of a family which had the sign of the authority.... now so far it maybe a little ambiguous, does this mean normal family, etc... but we will see Quran elaborates and elaborates on this subject with leaving no room for ambiguity.
