The word(s) "slaying" appears 2 time(s) in 2 verse(s) in Quran in Muhammad Habib Shakir translation.

(1) Then his mind facilitated to him the slaying of his brother so he slew him; then he became one of the losers

(2) And do not kill any one whom Allah has forbidden, except for a just cause, and whoever is slain unjustly, We have indeed given to his heir authority, so let him not exceed the just limits in slaying; surely he is aided.
