And you multiply it by six; it becomes twenty-seven. You pay seven to the legatee, and from it take half of the remainder of the third; six remain with him, and twenty-one remain, with seven for each son. This is so because the third after the bequest is the half after the share. Whenever he expresses an exception generally without saying "after the share" or "after the bequest," then according to the majority it is attributed to what is after the share, while according to Muhammad ibn al-Hasan and the Basrians, it is after the bequest.

Section: If he says: "except one-fifth of what remains of the estate after the share," and to another, a third of what remains of the estate after the first bequest, take the denominator, five, and add its fifth to it; it becomes six. Deduct its third because of the bequest of the third; four remains, which is the share. Then take a share, add five to it, and deduct its third; four-fifths remain. Add this to the shares of the sons and multiply it by five; it becomes nineteen, which is the estate. Pay four to the first, and subtract from it one-fifth of the remainder, three, and one share remains with him. Then pay one-third of the remainder, six, to the other; twelve remains, with four for each son. By algebra, take an estate and remove a share from it, then recover from it one-fifth of the remainder; you then have an estate and one-fifth minus a share and one-fifth. Remove one-third of that from it, and there remains four-fifths of an estate minus four-fifths of a share, which equals three shares. Reconcile, equate, and expand; the estate becomes nineteen and the share becomes four. If you wish, you may say: the shares of the sons are three, which is the remainder of an estate after a third of it has gone. Add its half to it; it becomes four and a half shares and a bequest. The bequest is a share minus one-fifth of the remainder, which is half a share and one-fifth [of a share, and one-fifth] of a bequest. Drop it from the share; there remains one-fifth of a share and a tenth
