﴿ فَلَمَّا رَأَوْا۟ بَأْسَنَا قَالُوٓا۟ ءَامَنَّا بِٱللَّهِ وَحْدَهُۥ وَكَفَرْنَا بِمَا كُنَّا بِهِۦ مُشْرِكِينَ ﴾

“And then, when they [clearly] beheld Our punishment, they said: “We have come to believe in the One God, and we have renounced all belief in that to which we were wont to ascribe a share in His divinity!””

Then when they saw Our doom that is the severity of Our chastisement they said ‘We believe in God alone and we disavow what we used to associate with Him’.
