Passing over of debts to someone else
1. You owe money to Shafî‘ah while Râbi‘ah owes you money. Shafî‘ah asked you for the money which you owe her. You reply: “Râbi‘ah is owing me some money. Take the money which I owe you from her and do not ask me.” If Shafî‘ah agrees to this there and then, and Râbi‘ah also agrees to this, then you are absolved from the responsibility of your debt to Shafî‘ah. Shafî‘ah cannot ask you for the money; she will have to ask Râbi‘ah, irrespective of when she receives the money. Furthermore, the money that you have asked Shafî‘ah to collect from Râbi‘ah, you cannot claim that amount from Râbi‘ah. However, if Râbi‘ah is owing you more than what you were owing Shafî‘ah, you can claim the balance from Râbi‘ah. If Râbi‘ah pays the money to Shafî‘ah, well and good. But if she did not pay and passes away, then Shafî‘ah will be paid after selling all her (Râbi‘ah’s) personal belongings. If Râbi‘ah did not leave behind any wealth or possessions or, while she was alive she denied owing you any money, took an oath that she owes no money to you, and there are no witnesses in this regard as well, then in such a case Shafî‘ah can ask you for the money that you owe her and can also demand it from you.
If in the very beginning you ask Shafî‘ah to take the money from Râbi‘ah and she does not agree, or Râbi‘ah herself is not happy about giving the money to Shafî‘ah, then this debt has not fallen off your shoulders (i.e. you are still responsible to pay Shafî‘ah her money).
