الْإِيمَانُ فَوْقَ الْإِسْلَامِ بِدَرَجَةٍ وَ التَّقْوَى فَوْقَ الْإِيمَانِ بِدَرَجَةٍ وَ الْيَقِينُ فَوْقَ التَّقْوَى بِدَرَجَةٍ وَ لَمْ يُقْسَمْ بَيْنَ الْعِبَادِ شَيْءٌ أَقَلُّ مِنَ الْيَقِينِ.
“Belief is one degree higher than Islam. Piety is one degree higher than belief. Certainty is one degree higher above piety. Nothing is distributed among people so little as certainty is.”
