hearts
in Edition Clear Qur'an by Talal Itani / Ghafir (The Forgiver)

40:18And warn them of the Day of Imminence, when the hearts are at the throats, choking them. The evildoers will have no intimate friend, and no intercessor to be obeyed.

40:19He knows the deceptions of the eyes, and what the hearts conceal.

40:56Those who dispute regarding God’s revelations without any authority having come to them—there is nothing in their hearts but the feeling of greatness, which they will never attain. So seek refuge in God; for He is the All-Hearing, the All-Seeing.
