Translation for 16:106

مَن كَفَرَ بِٱللَّهِ مِنۢ بَعۡدِ إِيمَٰنِهِۦٓ إِلَّا مَنۡ أُكۡرِهَ وَقَلۡبُهُۥ مُطۡمَئِنُّۢ بِٱلۡإِيمَٰنِ وَلَٰكِن مَّن شَرَحَ بِٱلۡكُفۡرِ صَدۡرٗا فَعَلَيۡهِمۡ غَضَبٞ مِّنَ ٱللَّهِ وَلَهُمۡ عَذَابٌ عَظِيمٞ ١٠٦
Whoever disbelieves in Allah after their belief—not those who are forced while their hearts are firm in faith,1 but those who embrace disbelief wholeheartedly—they will be condemned by Allah and suffer a tremendous punishment.

 This refers to ’Ammâr ibn Yâsser, an early revert to Islam, who was tortured to leave Islam. To save his life, ’Ammâr pretended to denounce Islam, but his heart was full of faith. When he told the Prophet (ﷺ) about what happened, this verse was revealed, reassuring him that his faith was intact.
