Mutarrif on Sincerity: True servants of Allah are pure inwardly, outwardly

Ibn al-Sari reported: Mutarrif, may Allah have mercy on him, said, “Verily, when the inward state of the servant matches his public behavior, Allah says: This is my true servant.”

عن ابن السري عَنْ مُطَرِّفٍ رحمه الله قَالَ إِنَّ الْعَبْدَ إِذَا اسْتَوَتْ سَرِيرَتُهُ وَعَلَانِيَتُهُ قَالَ اللَّهُ هَذَا عَبْدِي حَقًّا
