Qala inna feeha lootan qaloo nahnu aAAlamu biman feeha lanunajjiyannahu waahlahu illa (surah Ankabut: 32)

Tafseer Tafheem-ul-Quran by Syed Abu-al-A'la Maududi

(29:32) Abraham said: 'But Lot is there.' *55 They replied: 'We are well aware of those who are there. We shall save him and all his household except his wife.' His wife is among those who will stay behind. *56

Qaala inna feeha Lootaa; qaaloo nahnu a`lamu biman feehaa lanunajjjiyannahoo wa ahlahooo illam ra atahoo kaanat minal ghaabireen

*55) According to the initial part of this story as related in Surah Hud, the Prophet Abraham at first was perturbed to see the angels in human shape, for he knew that the coming of the angels in human shape was always a prelude to some dangerous mission. Then, when they gave him the good news, his fear wasallayed and he came to know that they had been sent to the people of Lot. Then he began making entreaties of mercy for those people (Hud: 7475), but his entreaties were not granted, and it was said: "Do not plead for them any more: your Lord's decree has been issued, and the punishment now cannot be averted." (v. 76) After this answer, when the Prophet Abraham lost all hope of any increase in the respite of Lot's people, he became anxious about the Prophet Lot himself, and said, what has been related here: "There is Lot in it." That is, "If the torment comes down when Lot is there, how will he and his household retrain safe from it?"
*56) According to Surah Tahrim: 10, this woman was not faithful to the Prophet Lot. Tha is why it was decreed that she too, would be afflicted with the torment in spite of being a Prophet's wife. Most probably when the Prophet Lot had come to Jordan after the migration and settled there, he might have married among the ,people living there. But the woman did not believe even after spending a lifetime with him, and her sympathies remained with her own people. As Allah has no consideration for relationships and brotherhoods and every person's case is decided on the basis of his own faith and morality, even being a Prophet's wife did not profit her in any way and she met her doom along with her own people with whom she had remained attached in faith and morality.
