﴿ 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) which came to destroy them, (they said: We believe in Allah only and reject (all) that we used to associate (with Him)) but this was said with their tongues only when they saw the punishment, but their hearts still did not believe.
