What is the procedure for emancipation when freeing a number of slaves whose total value constitutes exactly one-third of one's total property, and the slaves have equal value?

If the number of slaves whose value equals one-third of the estate is divisible by three (e.g., three, six, or nine), three parts must be made: one for freedom (hurriyyah) and two for remaining as property (riq). Three slips are made: one marked 'freedom' and two marked 'property.' These are placed under cover. A third party draws a slip. If the 'freedom' slip is drawn, that corresponding portion of the slaves is freed, and the remaining two portions remain as property. If a 'property' slip is drawn, that portion remains property, and another draw is made on the remaining portion. If the 'freedom' slip is drawn then, the third portion is freed; otherwise, the third portion remains property, as freedom has been designated among them. Alternatively, the name of each portion can be written on a slip, and drawing the 'freedom' slip results in the emancipation of those named, while the rest remain slaves.
