Possessing doubts...
Possessing doubts, questions, and satanic whispers and then going forth to remove the doubts and answering the questions is without a doubt, one of the necessities of the thought process of a human being and as long as doubts and questions remain with a person and they force him to reach a level of knowledge and certainty on those issues, such things remain blessed and praiseworthy. 3.
Doubts, misgivings and questions in regard to the teachings of the faith do not automatically result in apostasy.
Rather, apostasy is denial – with full knowledge – of the principles of the religion (Usul ad-Din) or one of the necessities (Dharuriyat) and clear and accepted (Badihiyat) teachings of the faith such that the denial of those clear and accepted things would lead to a denial of the Usul ad-Din and the person who is denying such things is fully aware of this relationship (between denying the necessities (Dharuriyat) and clear and accepted (Badihiyat) teachings of the faith) and being considered as an apostate.
The ruling for apostasy does not go against the principle of freedom of thought as if the who is conducting research does so with the purpose of searching out the truth and even if he does not reach to the realities – he would be considered as one who is not blameworthy (Qasir) – not culpable (Muqassir). In the presence of Allah, he would be pardoned, rather, he would be rewarded (for his efforts). The ruling for apostasy also does not go against the freedom of speech.
The person who becomes an apostate is able to, without openly expressing his apostasy, pose questions and present his own proofs (in regards to the rejection of faith) in religious gatherings and can request the scholars to provide answers to his questions.
