A trustee bearing the sin if they did not fulfill the will

Q 1: What is the ruling if the will is not executed? Will that cause any harm to the dead person?

A: Attorneys of Shar`y (Islamic legal) wills have to execute them. In case that they do not do so or they execute the wills badly, they - the attorneys - will bear the sin of it. Allah (Exalted be He) says: (Part No. 16; Page No. 370)  Then whoever changes the bequest after hearing it, the sin shall be on those who make the change. Truly, Allâh is All-Hearer, All-Knower. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
