2 verses have
mankind
in Edition Clear Qur'an by Talal Itani / Yunus (Jonas)

10:2Is it a wonder to the people that We inspired a man from among them: “Warn mankind, and give good news to those who believe that they are on a sound footing with their Lord”? The disbelievers said, “This is a manifest sorcerer.”

10:19Mankind was a single community; then they differed. Were it not for a prior decree from your Lord, the matters over which they had disputed would have been settled.
