Narrated 'Amr bin Shu'aib on his father's authority from his grandfather (RA):
Allah's Messenger (ﷺ) said: "One who kills a man cannot inherit anything from him."

[Reported by an-Nasa'i and ad-Daraqutni. Ibn 'Abdul-Barr graded it Qawiy (strong), while an-Nasa'i declared it to be defective. The right opinion is that it is Mawquf (a saying of a Companion) from 'Umar].
