Quran 5:27 — The Feast (Al-Ma'edah)

Recite for them the true history of Adam's two sons. They made an offering, and it was accepted from one of them, but not from the other. He said, "I will surely kill you." He said, "GOD accepts only from the righteous.

[5:26] He said, "Henceforth, it is forbidden them for forty years, during which they will roam the earth aimlessly. Do not grieve over such wicked people."

[5:28] "If you extend your hand to kill me, I am not extending my hand to kill you. For I reverence GOD, Lord of the universe.
