Man, by nature, cannot recognize his own self, relish peacefulness of the soul, nor can his heart be reassured except by worshiping Allah. {Those who believe and whose hearts find tranquility in the remembrance of Allah, for indeed in the remembrance of Allah do hearts find tranquility.} [Surat ar-Ra’d: 28]
Worship gives tranquility to the soul: {We know that you are distressed by what they say. Glorify your Lord with praise and be among those who prostrate [to Him], and worship your Lord} [Surat al-Hijr: 97-98]. Worship your Lord so that your heart is reassured.
That is why offering two rak’ahs with devotion and submissiveness does to the human soul what hours of psychological calming sessions fail to do. Verily, worship inspires tranquility to the human soul, and anyone who is distant from the remembrance of Allah suffers restlessness. You will find him always longing for worldly gains, yet he is neither satiated nor reassured. {But whoever turns away from My Reminder will have a miserable life} [Surat Taha: 124]. No matter how well-off a person may be, without faith, he will have a life of distress, and he will engage in an unending frantic race with the unknown.
No matter how well-off a person may be, without faith, he will have a life of distress, and he will engage in an unending frantic race with the unknown. You will always see him anxious.
