QS. Al-Ma'idah [5:32]

min ajli dzaalika katabnaa 'alaa banii israa‑iila annahu man qatala nafsan bighayri nafsin aw fasaadin fii al‑ardhi faka‑annamaa qatala alnnaasa jamii'an waman ahyaahaa faka‑annamaa ahyaa alnnaasa jamii'an walaqad jaa‑at‑hum rusulunaa bilbayyinaati tsumma inna katsiiran minhum ba'da dzaalika fii al‑ardhi lamusrifuuna

Because 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. [32]
