How do I respond to the شبهات (misconceptions/specious arguments) and doubts about the religion raised by Christians?

It is not permissible for a Muslim to engage in dialogue with disbelievers regarding their specious arguments without knowledge that enables him to refute falsehoods and clarify the truth. If a person fears for his religion due to residing among disbelievers, it is obligatory for him to relocate from them. If a Muslim encounters a specious argument for which he does not know the answer, he must ask the people of knowledge.
