The door of
Allah�s mercy is always open to all sinners, including those who have
been guilty of the most heinous of all sins, forsaking one�s faith-as
long as one is returns to Him in sincere repentance and making amends:
Allah says:
"But if any of you should turn away from his faith and
die as a denier of the truth - these it is whose works will go for
nought in this world and in the life to come; and these it is who are
destined for the fire, therein to abide." (Qur'an: 2: 217).
However, if someone repents and returns to Islam, and makes amends,
and leads a virtuous life, Allah will forgive him; Allah says,
"How would God bestow His guidance upon people who have
resolved to deny the truth after having attained to faith, and having
borne witness that this Apostle is true, and [after] all evidence of the
truth has come unto them? For, God does not guide such evildoing folk.
Their requital shall be rejection by God, and by the angels, and by all
[righteous] men. In this state shall they abide; [and] neither will
their suffering be lightened, nor will they be granted respite. But
excepted shall be they that afterwards repent and put themselves to
rights: for, behold, God is much-forgiving, a dispenser of grace."
(Qur'an: 3: 86-89).
The occasion of the revelation of the above verse, as reported by
Ibn Abbas, was the following: A man from the tribe of Ansar (in Madinah)
who had embraced Islam reverted to paganism; but later he became
remorseful about his action and sent someone to ask the Prophet (peace
be upon him) if he had any hope of being saved; accordingly, Allah
revealed the above verse. It clearly establishes the principle that if
an apostate returns to Islam and makes amends, and redeems himself
through good works he will be forgiven by Allah.
Therefore, it behooves you to cherish your faith and strive to be
steadfast in it, and ask Allah for help in doing so. You are also
advised to be friends with conscientious Muslims and try to join the
good works they are doing. For as the Prophet (peace be upon him)
reminds us that Devil always preys on those who isolate themselves even
as a wolf attacks the stray the sheep.
You may benefit from the experiences of a number of Christian pastors
and priests who have embraced Islam after being exposed to the truth.
