Recite for them the news of Adam's two sons in truth. They had both made an offering, and it was accepted from one of them, and not accepted from the other. He said, "I will kill you!"; he said, "God only accepts from the righteous."

[5:27] Killing a human intentionally without justice, is equivalent to killing all of humanity (5:32), since if one loses his respect for the life of one human being he will lose his respect for the basic principle of the unity of humanity. For the Biblical version of this story, see Genesis 4:1-25; Joshua 15:57; Hebrews 11:4; 1 John 3:12; Jude 1:11.
