The word(s) "hearts" appears 130 time(s) in 121 verse(s) in Quran in Muhammad Pickthal translation.

(51) Then, after him, We sent messengers unto their folk, and they brought them clear proofs. But they were not ready to believe in that which they before denied. Thus print We on the hearts of the transgressors.

(52) And Moses said: Our Lord! Lo! Thou hast given Pharaoh and his chiefs splendour and riches in the life of the world, Our Lord! that they may lead men astray from Thy way. Our Lord! Destroy their riches and harden their hearts so that they believe not till they see the painful doom.

(53) I say not unto you: "I have the treasures of Allah" nor "I have knowledge of the Unseen," nor say I: "Lo! I am an angel!" Nor say I unto those whom your eyes scorn that Allah will not give them good - Allah knoweth best what is in their hearts - Lo! then indeed I should be of the wrong-doers.

(54) For him are angels ranged before him and behind him, who guard him by Allah's command. Lo! Allah changeth not the condition of a folk until they (first) change that which is in their hearts; and if Allah willeth misfortune for a folk there is none that can repel it, nor have they a defender beside Him.

(55) Who have believed and whose hearts have rest in the remembrance of Allah. Verily in the remembrance of Allah do hearts find rest!

(56) Our Lord! Lo! I have settled some of my posterity in an uncultivable valley near unto Thy holy House, our Lord! that they may establish proper worship; so incline some hearts of men that they may yearn toward them, and provide Thou them with fruits in order that they may be thankful.

(57) As they come hurrying on in fear, their heads upraised, their gaze returning not to them, and their hearts as air.

(58) Thus do We make it traverse the hearts of the guilty:

(59) Your Allah is One Allah. But as for those who believe not in the Hereafter their hearts refuse to know, for they are proud.

(60) And Allah brought you forth from the wombs of your mothers knowing nothing, and gave you hearing and sight and hearts that haply ye might give thanks.
