Shiavault - a Vault of Shia Islamic Books Hayat Al-Qulub Vol.3 Part 3: Those who have the knowledge of Quran are the Imams In the description that those who have the knowledge of the Quran and who are perfect in knowledge and who fear the Quran are the Imams Ibne Mahyar has, through reliable sources, quoted Imam Baqir (a.s.) explaining the verse: فَالَّذِينَ آتَيْنَاهُمْ الْكِتَابَ يُؤْمِنُونَ بِهِ وَمِنْ هَؤُلَاء مَنْ يُؤْمِنُ بِهِ.
(As to) those whom We gave the Book before it, they are believers in it. (Sura Qasas 28:52) In this verse, what is meant by ‘those who are given the book’ are Aale Muhammad (a.s.) who have been given the knowledge of Quran. And some from this group are those who have believed in the book, the Hazrat said that Ahle Imaan means some people of the tribe.
Kulaini and others have, from many sources reported that in explanation of the Verse: بَلْ هُوَ آيَاتٌ بَيِّنَاتٌ فِي صُدُورِ الَّذِينَ أُوتُوا الْعِلْمَ. Nay! these are clear communications in the breasts of those who are granted knowledge... (Sura Ankabut 29:49) Imam Sadiq (a.s.) said: Some clear signs (verses) of Quran are in the hearts of those who have been given the knowledge, are the holy Imams from Aale Muhammad (a.s.) and in their hearts are both the words and the meanings of the Quran.
In Basairud Darajat , through reliable chains of narrators, Abu Baseer reports that Imam Baqir (a.s.) recited this verse and then said: Allah has not said that the Mushaf (text of Quran) is between two hardboard covers. Rather He has said that it is in the hearts of those who have been given the knowledge of it. Abu Baseer asked: are you those people? The Imam replied: Who else can be? This narration is quoted with nearly twenty chains showing that this verse is describing their greatness.
It is also possible that what is meant by the aforementioned verse by the Hazrat is that the clarification of Quran is in the hearts of the Imams and that none else knows its meanings and secrets. Therefore only they must be approached for understanding the Quran properly. Ayyashi has, quoted Imam Sadiq (a.s.) as saying in the explanation of the verse: الَّذِينَ آتَيْنَاهُمْ الْكِتَابَ يَتْلُونَهُ حَقَّ تِلَاوَتِهِ أُوْلَئِكَ يُؤْمِنُونَ بِهِ.
Those whom we have given the Book recite it as it should be recited and only they are the ones who have faith in it.
