How can one regain their previous religious commitment and devotion, and what is the ruling on prayers missed due to work circumstances?

The questioner is advised to search for the reason behind substituting the better for the worse. If the reason is being preoccupied with worldly matters, then this is an action in which there is no good, for prayer is the pillar of religion and the head of the matter. The Prophet, peace and blessings be upon him, warned against neglecting it, so work should not conflict with prayer. Scholars differed regarding the ruling on one who intentionally abandons prayer; some believe he is a disbeliever, while others consider it a lesser disbelief. In any case, missed prayers must be made up with sincere repentance and abundant seeking of forgiveness, and one should stay away from bad company and accompany righteous people.
