A. Yusuf Ali:Translation:
He said: "But there is Lut there." They said: "Well do
we know who is there : we will certainly save him
and his following,- except his wife: she is of those
who lag behind!" 3454

Muhammad Asad:Translation:
[And when Abraham] exclaimed, “But Lot lives there!” - they answered: We know fully well who is there; most certainly we shall save him and his household - all but his wife: she will indeed be among those that stay behind.” 27
3454 She was not loyal to her husband. Tradition says that she belonged to the wicked people, and was not prepared to leave them. She had no faith in the mission either of her husband or of the angels who had come as his guests.
