This question already has an answer here:
In Quran, there are many verses talking about Islam and on the other hand many others talk about Iman.
So We brought out whoever was in the cities of the believers. And We found not within them other than a [single] house of Muslims.
فأخرجنا من كان فيها من المؤمنين (*) فما وجدنا فيها غير بيت من المسلمين
Can someone tell me what is the difference between?
