Dought & clear, - Rulings on Tawbah, - Repentance From Spreading Anti-Islamic Materials.

I was a misguided person spreading secularist ideologies, and writing
heretical stories and articles, and using my poetry as a vehicle to
spread corruption and liberalism. Then Allah turned to me with His
mercy and brought me forth from darkness intolight. Now how shall I
repent?
Praise be to Allah.
This of course is a great blessing of Allah and a favor. We pray to
Allah that He grant you perseverance.
As for those who were engaged with their tongue and their pen in a war
against Islam by spreading distorted ideologies and doctrines, or by
spreading misguided innovations and corruption, the following is
incumbent upon them:
Announce their repentance and renounce all that they used to spread in
antagonism to Islam, in order that the renunciation becomes well
known, and so that no one can claim to be misguided by their disowned
writings. This renunciation is an obligation and is a precondition for
the acceptance of repentance. Allah says (what means): "Save for those
who repent, make amends and show clearly [what they used to say/rule
wrongly], it isthose whom I accept their repentance, and I am very
Forgiving, very Compassionate." [2:160] The tafseer (explanation) for
this verse indicates that it was revealed regarding the scholars of
ahl ul-kitab (People of the Book) who used to conceal what had been
revealed regarding the signs of the Prophet (peace be upon him) and
the commands to believe in him. They should from now on engage
themselves in the spread of the truth of Islam, spending their
energies in defense of its teachings, and educating people in their
religion. They should use their power of speech or writing to
counterattack the forces of falsehood, to expose their deceits, plans
and strategies, even as he used to co-operate with them in opposing
Islam, and thus become a sword in the defense of Islam. It is also
binding on he who convinced another man, even if in a private meeting,
against things declared haram (forbidden) by Islam, such as, for
instance, taking interest,to get in touch with the person he was
instrumental in changing his opinion and let him know of his own
renewed enlightenment.
And Allah knows best.
