There is peace in self trust because it stabilises. Peace in being self assured because it acts as a fortress. A fortress that keeps at bay all what’s not yours.
There is peace in these things when not the by product of arrogance or delusion.
Inner peace is the foundation of such self trust and self assurance. It’s grace from Allah who is a witness to the routes one took to arrive at its destination. Routes often denied by others because they didn’t witness it. Routes consisting of empathy, god consciousness, patience and integrity.
Self trust frees you from judging others because they judged you, or are prone to judge you.
“Qalaa Salama” Is an attribute of the believer because it’s deep rooted in Self trust.
