So We saved him and his family, except for his wife; she was of those who remain-Quran Verses

7-Surah Al-A’raf (The Heights ) 83

So We saved him and his family, except for his wife; she was of those who remained [with the evildoers].

﴿83﴾فَأَنجَيْنَاهُ وَأَهْلَهُ إِلَّا امْرَأَتَهُ كَانَتْ مِنَ الْغَابِرِينَ

Quran's Tafhim ( explanation)

*66). As the Qur'an mentions elsewhere, Lot's wife supported her disbelieving relatives to the last.* Hence, when God directed Lot and his followers to migrate from that corrupt land, He ordained that Lot's wife be left behind.
*This seems to be an inference from al- Tahrim 66: 10 - Ed.
