Section: If he combines a marriage and a sale, saying, "I have married you to my daughter, and sold you [this slave of mine] for one thousand," it is valid, and the thousand is apportioned between them according to her dowry and the value of the slave. If he says, "I have married you to my daughter, and purchased this slave of yours from you for one thousand," and the other says, "I have sold it to you, and I have accepted the marriage," it is valid, and the thousand is apportioned between the slave and the dowry of her likeness. Al-Shafi'i said, in one of his two opinions: The sale [and the dowry] are not valid, due to its leading to ambiguity (jahala). Our argument is that these are two contracts, each of which is valid on its own, so their combination is valid, just as if he had sold him two garments. If he says, "I have married you and [given you] this thousand for two thousand," the dowry is not valid, because it is like the issue of a mudd of dates.

Section: If he marries her for one thousand if her father is alive, and for two thousand if her father is dead, the naming is invalid, and she is entitled to the dowry of her peers. Ahmad explicitly stated this in a report by Muhanna, because the state of the father is not known, so it is unknown. If he says, "I have married you for one thousand if I do not remove you from your house, and for two thousand if I remove you from it," or "for one thousand if I do not have a wife, and for two thousand if I have a wife," Ahmad explicitly stated the validity of the naming in these two issues. Al-Qadi and Abu Bakr said: There are two reports regarding all of them. One is that it is not valid. Abu Bakr preferred this, because its path is the path of two conditions, so it is not permitted, like in a sale. The second report is that it is valid, because the one thousand is known, and only the second is unknown, being contingent upon a condition. If the condition is met, it is an addition to the dowry, and addition is permitted in a dowry. The first is more appropriate. The claim that this is a suspension on a condition is not valid for two reasons: one of them is that the addition cannot be validly suspended on a condition; if he were to say, "If your father dies..."
