Is it permissible for me to follow the teachings or fatwas of a particular Islamic scholar if, after research and scrutiny, they appear to me to be more correct?

The layperson must ask scholars and refer to the most reliable among them. As for the student of knowledge who is capable of understanding the evidence, he should adopt the opinion whose proofs are evident. One must be wary of those whom the scholars have warned against due to their deviance and aberration, such as Dr. Hassan Al-Turabi, who called for the unification of religions, denied the descent of Jesus (peace be upon him), claimed that not all companions were just, permitted apostasy, denied the infallibility of prophets and the stoning of the married fornicator, allowed a Muslim woman to marry a Jew or a Christian, denied the Houris of Paradise, and denied that the testimony of a man equals the testimony of two women. Therefore, it is advisable to be cautious of him and those like him, and to take one's religion from those whose piety and knowledge are trustworthy, as Ibn Sirin said: "Indeed, this knowledge is religion, so be careful from whom you take your religion."
