The most precious gift in human life is his religion and faith in his Lord. And indeed the faith of a person to his Lord, the attitude of justifying His promises and threats, obeying Him, obeying His apostle, doing the command and avoiding His prohibition is the fruit of faith by which happiness will be accomplished in the world and
luck and safety in the afterlife.
But faith can increase and decrease. Increased with obedience and reduced with disobedience. So humans are always required to be vigilant and try to make his faith not weak, less or even lost.
Among the weak factors of faith are:
Falling to sin and immorality
Hard heart
Lazy working on worship and obedience
Not affected by the Quran
Not angry when things that are forbidden by God are done
Mind with treasure
Reluctant to learn syar'i
Narrow minded
Inattentive
Love popularity
Leaving a pious example
Many are busy with the world
Many are busy with wives and children
