The phenomenon of weak faith has become very widespread among Muslims, and many people complain about the hardness of their hearts. So often we hear the words, "I feel hardness in my heart," "I do not find any joy in worship," "I feel that my faith has hit rock bottom," "Reading Qur'aan does not move me," "I fall into sin so easily." The effects of this affliction can be seen in many people, and this problem is the cause of every disaster and adversity.
