Any one who, after accepting faith in Allah, utters Unbelief,- except under compulsion, his heart remaining firm in Faith - but such as open their breast to Unbelief, on them is Wrath from Allah, and theirs will be a dreadful Penalty. This because they love the life of this world better than the Hereafter: and Allah will not guide those who reject Faith. Those are they whose hearts, ears, and eyes Allah has sealed up, and they take no heed. Without doubt, in the Hereafter they will perish.

(An-Nahl :106-109)
