O youth: so what have you gained from the acquisition of the science of dogmatic theology and from disputation and medicine and “diwans” and poetry and astronomy and prosody and syntax and morphology except squandering life?

By the splendor of the Possessor of splendor, assuredly I saw in the gospel of ‘Isa, upon our Prophet
and upon him be peace, (that) he said:

“From the moment in which the dead is placed on the bier until he is placed on the edge of the
tomb Allah the Exalted in His Majesty will ask him forty questions; the first is, He will say: ‘O my servant, you have purified (yourself in) the sight of mankind for years and not for one hour have you purified (yourself in) my sight, while every day I look in your heart; so I say, for what you do for another, while you are encompassed by my good gifts, are you not deaf, unheeding?
