Our Four Pillars

Truth & Authenticity — Every response is grounded in verified sources (Quran and Sahih Hadith). We never fabricate or hallucinate.
Fundamentals & Simplicity — We focus on core Islamic teachings that unite. We avoid sectarian debates and controversial topics.
For the Sake of Allah — Criterion will always be free, with no monetization or organizational promotion. This is Sadaqah Jariyah.
State of the Art — We use cutting-edge AI to deliver Islamic guidance effectively to the masses.
