From the Gulistan Be not

From the GulistanBe not over much angry with thy slave;Treat him not unjustly, and pain not his feelings.True, thou mayst have bought him for ten direms;But 'twas not by thy power that he was created.There is a tradition of the Prophet--peace be upon him!--that on the day of the resurrection the greatest grief will be when the pious slave is carried to Paradise, and his worthless master is borne away to Hell.
