Imam ‘Ali (a.s.) said:
أَجَلُّ النِّعَمِ اَلْعافِيَةُ وَ خَيْرُ مادَامَ فِى الْقَلْبِ الْيَقيِنُ
The best favor is health and the best thing which could fill man’s heart is belief in God.1
Imam ‘Ali (a.s.) has actually referred to the greatest material and spiritual favors. Physical health is the greatest divine favor in the material realm and it is indispensable for an active and a happy and prosperous life. And among spiritual favors, nothing is higher than the light of belief and faith. It is the most illuminating light for the path of life and the most effective remedy for diseases of ignorance, humiliation, inferiority and taint . It bestows tranquility to the heart and the soul!
