3-165 Ahmad ibn Zyad ibn Ja’far al-Hamedany - may God be pleased with him - narrated that Ali ibn Ibrahim quoted his father, on the authority of Ibn Abi Umayr, on the authority of Hisham ibn Salim, on the authority of Aba Abdullah as-Sadiq (MGB),

“There are three groups of people who recite the Quran. First there are those who use the Quran to approach the rulers and act haughty with the people. They are of the residents of Hell. Secondly there are those who recite the Quran and memorize it bit by bit, but violate its limits. They are of the residents of Hell. Lastly, there are those who recite the Quran, develop it in their minds and act according to the strong decrees, believe in the similitudes, practice its obligatory deeds, consider allowed what it has allowed and forbid what it has forbidden. Thus, God protects them from the harms of the occasions of going astray. They are of the residents of Paradise. They can intercede on behalf of whomever they wish.”
