The obligation which is imposed by eating another person's bread and salt, or salt alone, or eating such things with another, is well known; but the following example of it may be new to some readers.--Yaạḳoob the son of El-Leyth Eṣ-Ṣaffár, having adopted a predatory life, excavated a passage one night into the palace of Dirhem the Governor of Sijistán, or Seestán; and after he had "made up a convenient bale of gold and jewels, and the most costly stuffs, was proceeding to carry it off, when he happened in the dark to strike his foot against something hard on the floor. Thinking it might be a jewel of some sort or other, a diamond perhaps, he picked it up and put it to his tongue, and, to his equal mortification and disappointment, found it to be a lump of rock-salt; for having thus tasted the salt of the owner, his avarice gave way to his respect for the laws of hospitality; and throwing down his precious booty, he left it behind him, and withdrew empty-handed to his habitation. The treasurer of Dirhem repairing the next day, according to custom, to inspect his charge, was equally surprised and alarmed at observing that a great part of the treasure and other valuables had been removed; but on examining the package which lay on the floor, his astonishment was not less, to find that not a single article had been conveyed away. The singularity of the circumstance induced him to report it immediately to his master: and the latter causing it to be proclaimed throughout the city, that the author of this proceeding had his free pardon, further announced that on repairing to the palace, he would be distinguished by the most encouraging marks of favour." Yaạḳoob availed himself of the invitation, relying upon the promise, which was fulfilled to him; and from this period he gradually rose in power until he became the founder of a Dynasty.[155]
