he may divorce her, in which case she would be entitled to half the dowry; or he may consummate the marriage with her, in which case she would be entitled to the dowry in full. Thus, the dowry here is an unsecured debt, and a transfer with respect to it is invalid.
His statement, “The debt being transferred need not be firmly established,” means that the debt being transferred—namely, the debt owed by the transferor—need not be firmly established. The debt owed by the person upon whom the transfer is made, however, is the debt owed by that person. Thus, if a contract-slave transfers his master to a firmly established debt owed to the contract-slave by someone else, the transfer is valid, because the debt being transferred need not be firmly established.
Likewise, if a husband transfers his wife, before consummation, to someone from whom he is owed her dowry, this is permissible. For example, a woman marries for a dowry of ten thousand riyals, and I am owed ten thousand riyals by a man. If I transfer her for ten thousand riyals to the man from whom I am owed payment, this is permissible, because my claim against that person is firmly established. The woman’s claim against me, however, is not firmly established, but this does not matter, since the firm establishment of the debt being transferred is not a condition. Nevertheless, before consummation, this woman has no right to demand her dowry from that man, though she knows that her entitlement is held by him.
Thus, the condition is that the transfer be made to a firmly established debt. If it is made to a specific asset, then it is an agency arrangement; if it is made to an unsecured debt, it is invalid. And if it is made to neither a debt nor a specific asset, then it is not a valid transfer; rather, it is an agency arrangement to borrow.
The second condition is stated in his words: “The two debts must correspond,” meaning the debt being transferred and the debt owed by the person upon whom the transfer is made.
His statement, “in type, description, due date, and amount,” means that they must correspond in four respects:
