O Kumayl, those who amass wealth are dead even though they may be living while those endowed with knowledge will remain as long as the world lives. Their bodies are not available but their figures exist in the hearts. Look, here is a heap of knowledge (and Amir al-mu'minin pointed to his bosom). I wish I could get someone to bear it. Yes, I did find (such a one); but either he was one who could not be relied upon. He would exploit the religion for worldly gains, and by virtue of Allah's favours on him he would domineer over the people and through Allah's pleas he would lord over His devotees. Or he was one who was obedient to the hearers of truth but {here was no intelligence in his bosom. At the first appearance of doubt he would entertain misgivings in his heart.
