فَلَمَّا رَأَوۡاْ بَأۡسَنَا قَالُوٓاْ ءَامَنَّا بِٱللَّهِ وَحۡدَهُۥ وَكَفَرۡنَا بِمَا كُنَّا بِهِۦ مُشۡرِكِينَ
When they saw Our punishment, they said, “We have (now) come to believe in Allah alone, and We have rejected everything we used to ascribe (to Him) as partners.”
فَلَمۡ يَكُ يَنفَعُهُمۡ إِيمَٰنُهُمۡ لَمَّا رَأَوۡاْ بَأۡسَنَاۖ سُنَّتَ ٱللَّهِ ٱلَّتِي قَدۡ خَلَتۡ فِي عِبَادِهِۦۖ وَخَسِرَ هُنَالِكَ ٱلۡكَٰفِرُونَ
But, their profession of faith was not (competent) to benefit them, once they had seen Our punishment - a customary practice of Allah that has been there all along in the matter of His servants - and hence, the disbelievers became the losers.
