13 verses have
hearts
in Edition Clear Qur'an by Talal Itani / At-Tawba (The Repentance)

9:8How? Whenever they overcome you, they respect neither kinship nor treaty with you. They satisfy you with lip service, but their hearts refuse, and most of them are immoral.

9:14Fight them. God will punish them at your hands, and humiliate them, and help you against them, and heal the hearts of a believing people.

9:15And He will remove the anger of their hearts. God redeems whomever He wills. God is Knowledgeable and Wise.

9:45Only those who do not believe in God and the Last Day ask you for exemption. Their hearts are full of doubts, so they waver in their doubts.

9:60Charities are for the poor, and the destitute, and those who administer them, and for reconciling hearts, and for freeing slaves, and for those in debt, and in the path of God, and for the traveler in need—an obligation from God. God is All-Knowing, Most Wise.

9:64The hypocrites worry lest a chapter may be revealed about them, informing them of what is in their hearts. Say, “Go on mocking; God will bring out what you fear.”

9:77So He penalized them with hypocrisy in their hearts, until the Day they face Him—because they broke their promise to God, and because they used to lie.

9:87They prefer to be with those who stay behind. Their hearts were sealed, so they do not understand.

9:93But blame is on those who ask you for exemption, although they are rich. They are content to be with those who stay behind. God has sealed their hearts, so they do not know.

9:110The structure which they built will remain questionable in their hearts, until their hearts are stopped. God is Knowing and Wise.

9:117God has redeemed the Prophet, and the Emigrants, and the Supporters—those who followed him in the hour of difficulty—after the hearts of some of them almost swerved. Then He pardoned them. He is Kind towards them, Compassionate.

9:125But as for those in whose hearts is sickness: it adds disgrace to their disgrace, and they die as unbelievers.

9:127And whenever a chapter is revealed, they look at one another, “Does anyone see you?” Then they slip away. God has diverted their hearts, because they are a people who do not understand.
