The word(s) "hearts" appears 132 time(s) in 121 verse(s) in Quran in Mohsin Khan translation.

(111) And those who came after them say: "Our Lord! Forgive us and our brethren who have preceded us in Faith, and put not in our hearts any hatred against those who have believed. Our Lord! You are indeed full of kindness, Most Merciful.

(112) They fight not against you even together, except in fortified townships, or from behind walls. Their enmity among themselves is very great. You would think they were united, but their hearts are divided. That is because they are a people who understand not.

(113) And (remember) when Musa (Moses) said to his people: "O my people! Why do you annoy me while you know certainly that I am the Messenger of Allah to you? So when they turned away (from the Path of Allah), Allah turned their hearts away (from the Right Path). And Allah guides not the people who are Fasiqun (the rebellious, the disobedient to Allah).

(114) That is because they believed, and then disbelieved; therefore their hearts are sealed, so they understand not.

(115) If you two (wives of the Prophet صلى الله عليه وسلم : 'Aishah and Hafsah رضي الله عنهما) turn in repentance to Allah, (it will be better for you), your hearts are indeed so inclined (to oppose what the Prophet صلى الله عليه وسلم likes); but if you help one another against him (Muhammad صلى الله عليه وسلم), then verily, Allah is his Maula (Lord, or Master, or Protector), and Jibril (Gabriel), and the righteous among the believers; and furthermore, the angels are his helpers.

(117) And We have set none but angels as guardians of the Fire. And We have fixed their number (19) only as a trial for the disbelievers, in order that the people of the Scripture (Jews and Christians) may arrive at a certainty [that this Qur'an is the truth as it agrees with their Books regarding the number (19) which is written in the Taurat (Torah) and the Injeel (Gospel)] and that the believers may increase in Faith (as this Qur'an is the truth), and that no doubt may be left for the people of the Scripture and the believers, and that those in whose hearts is a disease (of hypocrisy) and the disbelievers may say: "What Allah intends by this (curious) example ?" Thus Allah leads astray whom He wills and guides whom He wills. And none can know the hosts of your Lord but He. And this (Hell) is nothing else than a (warning) reminder to mankind.

(118) (Some) hearts that Day will shake with fear and anxiety.

(119) Nay! But on their hearts is the Ran (covering of sins and evil deeds) which they used to earn.

(120) Which leaps up over the hearts,
