And with the same chain of transmission on the authority of al-Asbagh ibn Nubatah that The Commander of the Faithful said: “Verily, concern about this world does not increase one’s gain, and that is a waste of effort. Verily, the arrival of the Hereafter does not decrease for what it estimated in (that is) the achievement of the Return.” He composed this: If in a stable rock in the ocean, Hard and solid, gathered with smooth sides, There is sustenance for a soul that Allah sees; it will split From it and brings to him all that is in it. Or if there was between the seven layers (of heavens) his junction Allah will ease its elevation in the difficult ascent, Until he takes that which is written for him in the guarded-tablet, The soul finds sustenance; otherwise sustenance will seek it out. The Compiler of this book says: Our sustenance includes everything which Allah, the Mighty and High, has made for our benefits, and which He has made accessible to us. Our sustenance does not extend to that which Allah, the Mighty and High, has made inaccessible for us.
