It is obligatory to settle the deceased's debts at first and then his will should be executed in the charitable ways within the limits of one third or less. The heirs must approve of a bequest that exceeds one third. His will to the daughters is not valid because of the Prophet's saying:
No will for an heir
However, this will would be valid if the inheritors agreed to it. The rest of money will be distributed to the heirs in the legal way after the debts are paid. (Part No. 16; Page No. 322) May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
