Does the Qur’an Support the Idea of Continuous Personal Reform?

[shahrukhkhan]

Salam all,


I've been reflecting on verses like Surah Ar-Ra'd 13:11 – "Indeed, Allah will not change the condition of a people until they change what is in themselves."

This seems to highlight personal responsibility and self-driven transformation. But I'm curious:
How far does the Qur'an encourage ongoing self-reform, even after one believes?

Is there a Qur'anic basis for the idea that faith requires constant re-evaluation and internal purification?

Appreciate your insights and Qur'anic references if possible.
