(2) باب تَعْظِيمِ الدَّمِ
It was narrated that Sa'eed bin Jubair said:
"The people of Al-Kufah differed concerning this Verse: "And whoever kills a believer intentionally." So I went to Ibn 'Abbas and asked him, and he said: 'It was revealed among the last of what was revealed, and nothing of it was abrogated after that.'"
