“heart”
in Edition Clear Qur'an by Talal Itani / An-Nahl (The Bee)
16:22Your God is one God. As for those who do not believe in the Hereafter, their hearts are in denial, and they are arrogant.
16:106Whoever renounces faith in God after having believed—except for someone who is compelled, while his heart rests securely in faith—but whoever willingly opens up his heart to disbelief—upon them falls wrath from God, and for them is a tremendous torment.
16:108It is they whom God has sealed their hearts, and their hearing, and their sight. It is they who are the heedless.
