In Quran, there are many verses talking about Islam and on the other hand many others talk about Iman.
And both of them are mentioned in the same verses like these verses 35&36 Adh-Dhariyat:
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?
