Sahih Bukhari | Volume 6 | Hadith Number 289

Narrated by Said bin Jubair
Abdur-Rahman bin Abza ordered me to ask Ibn 'Abbas regarding the two Verses (the first of which was):

And whosoever murders a believer intentionally." (4:93) So I asked him, and he said, "Nothing has abrogated this Verse." About (the other Verse): 'And those who invoke not with Allah any other god.' he said, "It was revealed concerning the pagans."
