﴿ مَن كَفَرَ بِٱللَّهِ مِنۢ بَعْدِ إِيمَٰنِهِۦٓ إِلَّا مَنْ أُكْرِهَ وَقَلْبُهُۥ مُطْمَئِنٌّۢ بِٱلْإِيمَٰنِ وَلَٰكِن مَّن شَرَحَ بِٱلْكُفْرِ صَدْرًۭا فَعَلَيْهِمْ غَضَبٌۭ مِّنَ ٱللَّهِ وَلَهُمْ عَذَابٌ عَظِيمٌۭ ﴾

“As for anyone who denies God after having once attained to faith-and this, to be sure, does not apply to one who does it under duress, the while his heart remains true to his faith, but [only, to] him who willingly opens up his heart to a denial of the truth-: upon all such [falls] God's condemnation, and tremendous suffering awaits them:”

Whoever disbelieves in God after having affirmed his faith — except for him who is compelled to pronounce a statement of unbelief and so pronounces it while his heart is at rest in faith man ‘whoever’ is either a subject or a conditional and so the predicate of this subject or the response to this conditional is an implied lahum wa‘īdun shadīd ‘there is for them a severe threat of chastisement’; this is indicated by the statement that follows — but he who opens up his breast to unbelief that is he who opens it up and expands it with unbelief meaning that his soul is content with it upon such shall be wrath from God and there is a great chastisement for them.
