Verified Reference for Ijma' on the prohibition of killing non-combatants

[ammardiwan]

As-salamu alaykum,

I am looking for something specific:
Which scholars have reported that there is ijma' on the prohibition of killing non-combatants in war

So I'm looking for:
"Such and such scholars have reported in such and such books that there is ijma' on the prohibition of killing non-combatants in war"

I don't want a discussion on Jihad.

Also, I request that only students of knowledge/scholars respond.

Also, please ensure that the reference is verified

Mufti soofi_saheb, would you be able to provide such a reference?
