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.
One of the most important principles which must be understood in order
to treat the problem of weak faith is that faith increases and
decreases, or waxes and wanes. This is one of the basic principles of
the ‘aqeedah of Ahl al-Sunnah wa’l-Jamaa’ah, who say that faith is
something to be spoken in words, to be believed in in the heart, and to
be put into action. Faith increases with obedience and decreases with
'… that they may grow more in Faith along with their (present) Faith…'
'… Which of you has had his faith increased by it? …'[al-Tawbah 9:124].
