Sparing is mentioned in the Quran in these verses:
[5:32] Because of this, we decreed for the Children of Israel that anyone who murders any person who had not committed murder or horrendous crimes, it shall be as if he murdered all the people. And anyone who spares a life, it shall be as if he spared the lives of all the people. Our messengers went to them with clear proofs and revelations, but most of them, after all this, are still transgressing.
[6:16] “Whoever is spared (the retribution), on that day, has attained His mercy. And this is the greatest triumph.”
[33:25] God repulsed those who disbelieved with their rage, and they left emptyhanded. God thus spared the believers any fighting. God is Powerful, Almighty.
[39:68] The horn will be blown, whereupon everyone in the heavens and the earth will be struck unconscious, except those who will be spared by God. Then it will be blown another time, whereupon they will all rise up, looking.
[44:56] They do not taste death therein – beyond the first death – and He has spared them the retribution of Hell.
[52:18] They enjoy what their Lord has reserved for them; their Lord has spared them the retribution of Hell.
