Translated by Sayyid Ali Reza

وَقَالَ (عليه ‏السلام):

Amir al-mu'minin, peace be upon him, said:

أَوْضَعُ الْعِلْمِ

The lowest form of knowledge

مَا وُقِفَ عَلَى اللِّسَانِ

is that which remains on the tongue

وَأَرْفَعُهُ

and the most superior form

مَا ظَهَرَ فِي الْجَوَارِحِ وَالاْرْكَانِ .

is that which manifests itself through (the action of) the limbs and the organs of the body.
