فَهَذَا دِينُنَا وَاعْتِقَادُنَا ظَاهِرًا وَبَاطِنًا وَنَحْنُ بُرَآءُ إِلَى اللَّهِ مِنْ كُلِّ مَنْ خَالَفَ الَّذِي ذَكَرْنَاهُ وَبَيَّنَّاهُ.
This is our religion and belief, outwardly and inwardly; before Allah we declare ourselves free of those who oppose the beliefs we have stated and explained.
Outwardly and inwardly requires agreement between what the tongue professes and what the heart believes. Religion is not simply an outward declaration; the declaration and inward conviction must be consistent.
