The residence is under all conditions the property of the first-born son, irrespective of whether or not the deceased should have left behind him other property as well. The first-born son receiveth, moreover, his share of the remainder of the estate. This is that which God hath prescribed. The testator is, however, at liberty while still alive to dispose of his property in whatsoever manner he seeth fit. Likewise, the first-born son must himself, for the sake of God, take into consideration the other heirs, and be just and fair to them. In truth, it is obligatory for everyone, by the express requirement of the divine text, to draw up a will, so that it may be implemented after he hath passed away. This, verily, is the perspicuous truth. If, God forbid, he disobeyeth the divine command—faileth, that is, to draw up a will—then his estate must be divided up in the stipulated manner.
