[Machine] It is said that faith is not about adornment or wishful thinking, but rather faith is what settles in the heart and is affirmed by actions.  

الزهد لأحمد:١٤٨٣ – حَدَّثَنَا عَبْدُ اللَّهِ حَدَّثَنَا اللَّيْثُ بْنُ خَالِدٍ أَبُو بَكْرٍ الْبَلْخِيُّ حَدَّثَنَا جَعْفَرُ بْنُ سُلَيْمَانَ عَنْ زَكَرِيَّا عَنِ الْحَسَنِ قَالَ كَانَ

يُقَالُ إِنَّ الْإِيمَانَ لَيْسَ بِالتَّحَلِّي وَلَا بِالتَّمَنِّي وَإِنَّمَا الْإِيمَانُ مَا وَقَرَ فِي الْقَلْبِ وَصَدَّقَهُ الْعَمَلُ
