Who is entitled to pay and receive the debts?

With regards to the condition that Amar is required to pay all the debts that are being owed by the business and that he is entitled to receive all the amounts that are being owed to the business, the Shar’i ruling is that by making such a condition the business debts will not be carried over to Amar and at the same time, Amar will not be entitled to receive the outstanding amounts that are being owed to the Business. Zaid (and not Amar) will be required to settle the outstanding debts being owed by the business just as Zaid himself will be entitled to receive the amounts that were being owed to the business. To make such conditions when selling a business etc. is not permissible.
