Hawzah News Agency – Is leaving a will obligatory so much so that one could be sinful if they do not do it?

A: Should the person keep other’s belongings or have in their possession some property that carries a liability, be it to the people or in the form of religious dues, of which they could not discharge their responsibility, it is obligatory on them to leave a will. Otherwise, it is not obligatory.
