We have divided the preemption according to that, and we did not grant the second purchaser nor Bakr anything by the shares entitled through preemption; because ownership based upon it is not established. The third [view]: if he forgives the preemption for them, they are entitled by it. If it is taken by preemption, they are not entitled to anything by it. If he forgives some of them but not others, the one forgiven is entitled by his shares, unlike the one not forgiven. That which the preemption became void for due to Amr's sale is in the position of that which was forgiven; thus, two views are derived regarding its amount. Had we investigated the branches of this issue in a way of elaboration, it would have been lengthy and led to boredom.

Section: If a house is between four people in equal parts, and two of them purchase the share of one of them, the fourth is entitled to preemption against them, and each of the two purchasers is entitled to preemption against the other. If each one of them demands his preemption, the sold property is divided between them in thirds, and the house becomes between them likewise. If the fourth alone forgives it, the sold property is divided between the two purchasers in halves. Likewise, if everyone forgives their preemption, three quarters of the house go to them, and the fourth keeps his quarter as it is. If the fourth alone demands it, he takes half of the sold property from them; because each one of them has the same amount of ownership as the claimant, so the preemption of his sold property is divided between him and his preemptor in halves, and the fourth comes to possess three eighths of the house, and the remainder of it is divided between the two in halves. The problem is correctly resolved from sixteen. If the fourth alone demands it from one of them without the other, he divides the price with him in halves, and the one forgiven comes to possess three eighths, and the remainder is between the fourth and the other in halves. The problem is correctly resolved from sixteen. If one of the two purchasers forgives it, and neither the other nor the fourth forgives it, the sold property of the one forgiven is divided between him and the fourth in halves, and the sold property of the other is divided between them in thirds. The one who did not forgive comes to possess a quarter and a third of an eighth—which is a sixth and an eighth—and the remainder is between the other two in halves. The problem is correctly resolved from forty-eight. If the fourth forgives one of them, and neither of them forgives the other, he takes a third of the price from the one who did not forgive, and the remainder is between the two of them in halves, and the fourth is like the one who forgives in the previous case. The problem is correctly resolved from forty-eight. If the fourth forgives,
