One son of Adam kills the other. The Quran uses it to teach that killing one person is like killing all people.
Qabil · Habil
Step into this storyFull screen, scene by sceneBecause of that, We decreed upon the Children of Israel that whoever kills a soul unless for a soul or for corruption [done] in the land - it is as if he had slain mankind entirely. And whoever saves one - it is as if he had saved mankind entirely. And our messengers had certainly come to them with clear proofs. Then indeed many of them, [even] after that, throughout the land, were transgressors.
