In Kafi and Basair ...

In Kafi and Basair , a conclusion is made that Shias do not know its interpretation but whenever anyone from those who are firmly rooted in knowledge tell it to them they say: We have put faith in it; that all of it is from Allah though the Holy Quran contains the special, common, clear, allegorical, abrogator, abrogated, everything and all of it is known to those who are those who are firmly rooted in knowledge.

[^3] Kulaini has, with true chains of narrators, quoted the Imam saying: We are the one firmly rooted in knowledge, we know the meaning of Quran and another reliable tradition says that the firmly rooted in knowledge is Amirul Momineen (a.s.) and after him the Imams (a.s.).

In Basairud Darajat , it is mentioned with reliable chains of narrators that Imam Baqir (a.s.) said: In the Holy Quran, there is not a single verse which does not have its outward and inward meaning and that there is not a single letter which is not a sign showing what is happening and its happening and appearing is being made known to the Imam of the time and its meaning is known to the living and present Imam and so also to the earlier Imam as Allah says: Its meaning is not known to anyone but Allah and those who are firmly rooted in knowledge and it is we who know it.

Similarly, while explaining the verse: وَيَرَى الَّذِينَ أُوتُوا الْعِلْمَ الَّذِي أُنزِلَ إِلَيْكَ مِنْ رَبِّكَ هُوَ الْحَقَّ. Those who have been given knowledge know what, O Messenger, has been revealed to you from your Lord. (Sura Saba 34:6) The Hazrat said that it means Amirul Momineen (a.s.) who has testified to whatever Allah sent to the Holy Prophet (S).

Kulaini has, with reliable chains of narrators, quoted Imam Baqir (a.s.) saying that no one has ever claimed but falsely that he knows the entire Quran as it has been revealed to the Holy Prophet (S) and that he has collected it and that he has remembered (learnt) it by heart except Ali Ibne Abi Talib (a.s.) and the Imams after him (they only have made such a claim truly).
