Jazak Allah khairan for your help
Answer: [By Dr. Saifullah]
Praise be to Allah.
We feel that you made a mistake in quoting the verse – it should be 2:180, instead of 2:170. This verse i.e. 2:180 was abrogated and the “hukm” is no longer valid (mansukh). Also, “waseeyat” and “will” are the same thing. You can make “waseeyat” to give away at the most one third of your property/possessions after your death to someone (or some organization like say, Madrasa etc) who is/are not due inheritor(s) of your property.
And Allah knows the best.
