The Hazrat said that Muhammad (S) was warning (about Allah’s anger) and so also do we.[^2] Ali bin Ibrahim has narrated with reliable chains of narrators from Imam Sadiq (a.s.) that the Holy Quran is the warner which creates love for Paradise and make one try to save oneself from Hell.
There are clear-cut verses which give clear evidence of the meaning and the aim. And there also are some verses which are not so clear (allegorical) from which many meanings can be derived.

(Sura Ale-Imran 3:7) And those who are perfect in knowledge are Aale Muhammad. Likewise, Ali bin Ibrahim, the author of Ikhtisas has, with reliable chains of narrators, quoted Imam Baqir (a.s.) saying that the Holy Prophet (S) was most perfect in the knowledge and he knew what Allah has sent to him in Quran and also its meaning, that is, he knew both the apparent and the hidden of the Holy Quran, it had never so happened that Allah sent him a verse but did not show him its meaning.
Similarly his legates who came after him also knew both the revelation and interpretation of the Holy Quran.
