Al-Mu'min (The Believer)
Surah 40 · Verse 22
That was because, their messengers had come to them with clear proofs but they rejected (them) so Allah caught them, He is certainly Strong, Severe in requital.
Qaroon was from Bani Israel but he did not believe in Musa (PBH) whereas there was a person from Firawn’s people who believed in Musa (PBH) and even argued with Firawn and his people in favour of Musa (PBH). This again shows that one’s being a Momin and a Muslim does not depend on one’s relationship with good or bad people see also Chapter:19 Verses 51-55 commentary.
