Al-Ma'idah 5:32 من اجل ذالك كتبنا على بني اسراييل انه من قتل نفسا بغير نفس او فساد في الارض فكانما قتل الناس جميعا ومن احياها فكانما احيا الناس جميعا ولقد جاءتهم رسلنا بالبينات ثم ان كثيرا منهم بعد ذالك في الارض لمسرفون ٣٢

For that cause We decreed for the Children of Israel that whosoever killeth a human being for other than manslaughter or corruption in the earth, it shall be as if he had killed all mankind, and whoso saveth the life of one, it shall be as if he had saved the life of all mankind. Our messengers came unto them of old with clear proofs (of Allah's Sovereignty), but afterwards lo! many of them became prodigals in the earth.

Because of that, We decreed upon the Children of Israel that whoever kills a soul unless for a soul¹ or for corruption [done] in the land² - it is as if he had slain mankind entirely. And whoever saves one³ - 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.⁴

On that account: We ordained for the Children of Israel that if any one slew a person - unless it be for murder or for spreading mischief in the land - it would be as if he slew the whole people: and if any one saved a life, it would be as if he saved the life of the whole people. Then although there came to them Our messengers with clear signs, yet, even after that, many of them continued to commit excesses in the land.
