“Beware lest ye scatter the pearls of inner significance before every barren, dumb one. Verily, the blind are deprived of witnessing the lights and are unable to distinguish between the stone and the holy, precious pearl.
“Verily, wert thou to read the most mighty, wonderful verses to the stone for a thousand years, will it understand, or will they take any effect therein? No! by thy Lord, the merciful, the clement! If thou readest all the verses of God unto the deaf, will he hear a single letter? No! Verily, by the beauty, the mighty, the ancient!
“Thus have We delivered unto thee some of the jewels of wisdom and utterance, in order that thou mayest gaze unto the direction of thy Lord and be severed from all the creatures. May the spirit and glory rest upon thee, and upon those who dwell upon the plain of holiness and who remain in the Cause of their Lord in manifest steadfastness!”
