The Impact of Calling to Allah Without Knowledge

Question:
May Allah reward you. Honorable Shaykh, religious knowledge is very important for the da'iyah (caller to Allah). One must acquire religious knowledge before calling people to Allah.

Answer:
Yes, we have mentioned this. We said that it is obligatory for him to understand the religion of Allah and learn the matters of the religion before he begins the call. Otherwise, what would he be calling people to if he does not know the matters of the religion? How can he call to Allah? He would be calling based on ignorance. Perhaps he would misguide people without realizing it. Perhaps he would forbid what is lawful, or permit what is forbidden, or issue a fatwa without knowledge. The da'iyah must be asked questions, and he must be required to provide answers to difficult issues. Therefore, he must be prepared. He will also face argument and dispute from the stubborn, and doubts that they raise. He must have knowledge to refute them, confront them, expose them, and falsify them. He cannot do this except with knowledge. Yes.
