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

(71) And those who give that which they give with hearts afraid because they are about to return unto their Lord,

(72) Nay, but their hearts are in ignorance of this (Qur'an), and they have other works, besides, which they are doing;

(73) He it is Who hath created for you ears and eyes and hearts. Small thanks give ye!

(74) Men whom neither merchandise nor sale beguileth from remembrance of Allah and constancy in prayer and paying to the poor their due; who fear a day when hearts and eyeballs will be overturned;

(75) Is there in their hearts a disease, or have they doubts, or fear they lest Allah and His messenger should wrong them in judgment? Nay, but such are evil-doers.

(76) Thus do We make it traverse the hearts of the guilty.

(77) But it is clear revelations in the hearts of those who have been given knowledge, and none deny Our revelations save wrong-doers.

(78) Thus doth Allah seal the hearts of those who know not.

(79) Then He fashioned him and breathed into him of His Spirit; and appointed for you hearing and sight and hearts. Small thanks give ye!

(80) Allah hath not assigned unto any man two hearts within his body, nor hath He made your wives whom ye declare (to be your mothers) your mothers, nor hath He made those whom ye claim (to be your sons) your sons. This is but a saying of your mouths. But Allah saith the truth and He showeth the way.
