﴿ ثُمَّ صَدَقْنَٰهُمُ ٱلْوَعْدَ فَأَنجَيْنَٰهُمْ وَمَن نَّشَآءُ وَأَهْلَكْنَا ٱلْمُسْرِفِينَ ﴾

“In the end, We made good unto them Our promise, and We saved them and all whom We willed [to save], and We destroyed those who had wasted their own selves.”

(Then We fulfilled the promise unto them) We fulfilled the promise given to the prophets that they will be saved. (So We delivered them) i.e. the prophets (and whom We would) and those who believed in the prophets, (and We destroyed the prodigals) and We destroyed the idolaters.
