Surah Adh-Dhariyat 51:36

فَمَا وَجَدْنَا فِيهَا غَيْرَ بَيْتٍ مِّنَ ٱلْمُسْلِمِينَ

And We found not within them other than a [single] house of Muslims.

Translation: Saheeh International

Tafsir

but We did not find therein other than one house of those who had submitted to God these were Lot and his two daughters. They have been described here with the terms ‘belief’ and ‘submission’ because they had affirmed faith in their hearts and used their limbs to perform acts of obedience.
