4 verses have
hearts
in Edition Clear Qur'an by Talal Itani / Muhammad (Muhammad)

47:16Among them are those who listen to you, but when they leave your presence, they say to those given knowledge, “What did he say just now?” Those are they whose hearts God has sealed, and they follow their own desires.

47:20Those who believe say, “If only a chapter is sent down.” Yet when a decisive chapter is sent down, and fighting is mentioned in it, you see those in whose hearts is sickness looking at you with the look of someone fainting at death. So woe to them!

47:24Will they not ponder the Quran? Or are there locks upon their hearts?

47:29Do those in whose hearts is sickness think that God will not expose their malice?
