وَالْإِيمَانُ وَاحِدٌ وَأَهْلُهُ فِي أَصْلِهِ سَوَاءٌ
Faith is one, and believers share its essential basis.
The essence of faith concerns affirmation in the heart. Believers share this fundamental basis, while their excellence in faith differs through God-consciousness, reverence, resistance to desire, and steadfast good conduct.
Sharing faith’s essence does not make everyone equal in practice or rank. Differences in piety also do not mean that every failing necessarily destroys the essential basis of faith.
