What are some Quran verses about judging others?

One Quran verse about judging others is from Surah Al-Hujurat, verse 12: "O you who have believed, avoid much negative assumption. Indeed, some assumption is sin. And do not spy or backbite each other. Would one of you like to eat the flesh of his brother when dead? You would detest it. And fear Allah; indeed, Allah is Accepting of repentance and Merciful." This verse emphasizes the importance of avoiding making negative assumptions about others and refraining from backbiting or spying on them.
