﴿ وَأُوحِىَ إِلَىٰ نُوحٍ أَنَّهُۥ لَن يُؤْمِنَ مِن قَوْمِكَ إِلَّا مَن قَدْ ءَامَنَ فَلَا تَبْتَئِسْ بِمَا كَانُوا۟ يَفْعَلُونَ ﴾

“AND THIS was revealed unto Noah: "Never will any of thy people believe except those who have already attained to faith. Be not, then, distressed by anything that they may do,”

(And it was inspired in Noah, (saying): No one of thy folk will believe save him who hath believed already. Be not distressed) do not be saddened for their destruction (because of what they do) in their state of disbelief.
