In another place, the Commander of the Faithful Imam `Ali ibn Abi Talib (peace be upon him) describes the Qur'an as follows:

"Then Allah (Glorified and Exalted is He) revealed to him (the Prophet (blessings of Allah be upon him and his progeny)) the Book.

• It is a light whose radiance shall not be extinguished;
• A lamp whose flame shall not die;
• An ocean whose depth shall not be fathomed;
• A path which shall not lead astray;
• A blaze whose brilliance shall not be darkened;
• A criterion whose evidence shall not be suppressed;
• An elucidation whose cornerstones shall not be demolished;
• A cure with which there is no fear of ailments;
• A power whose supporters cannot be defeated;
• A truth whose helpers will not be forsaken.
• Thus, it is the source of faith and its prosperity;
• It is the fountain-head of knowledge and its vastness;
• The meadow of justice and its flowing streams;
• The support of Islam and its foundation;
• The valleys of the truth and its fields;
• An ocean that shall not be drained by those who draw upon it;
• A spring that shall not be exhausted by those who draw from it;
• A watering place that shall not be depleted by those who come to it;
• A station whose road the travelers do not miss;
• A signpost which the wayfarers will always see;
• The hilltops that cannot be bypassed by those who seek them.
• Allah (Glorified and Exalted is He) has made it the quencher of the thirst of scholars,
• A vernal season for the hearts of the jurists,
• A destination for the path of the righteous,
• A cure after which there is no malady,
• A light which does not alternate with darkness,
• A rope whose knots are firm,
• A stronghold whose peak is impregnable.
• It is power for whoever cultivates it,
• Peace for whoever dwells on it,
• A guidance for whoever follows it,
• A laudable act for whoever embraces it,
• An argument for whoever speaks for it,
• A witness for whoever fights for it,
• A sharp instrument for whoever bases his arguments on it,
• A support for whoever supports it,
• A means of deliverance for whoever employs it,
• A sign for the discriminating, a shelter for whoever seeks healing,
• A source of knowledge for whoever has sense,
• And the best narrative for its transmitters,
• And a means for the one who sits in judgment."
