Permissibility of continuing to pay Sadaqah of more than one third of the deceased's money with the heir's permission

Q 4: If a pious man used to give Sadaqah (voluntary charity) to the poor before he died from cancer, is it permissible for his brother to continue giving money as Sadaqah Jariyyah (ongoing charity) on his behalf?

A: If the deceased had written in his will that he wants his money to be spent in Sadaqah, (Part No. 16; Page No. 288) his will should be carried out, provided that it does not exceed one third of his money. If he had not written a will, his money is distributed among the heirs according to Shari`ah (Islamic law). If one or more of the heirs give their inheritance as Sadaqah on behalf of the deceased, it is fine and they will be rewarded for it in Shaa' Allah (if Allah wills). May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
