What is the guidance for one who wishes to combine seeking knowledge with da'wah?

Question : This questioner says: Honorable Shaykh, what is your view, or rather your guidance, for one who wants to combine seeking knowledge with calling others to Islam?

Answer : The guidance here is to strive to seek knowledge, meaning that he should spend most of his attendance and most of his time in seeking knowledge, but he should not neglect da'wah. This is because his knowledge will be sincere only if he has da'wah, and if he calls to Allah without knowledge, he may misguide and be misguided. For most people, when someone steps forward and speaks to them, they come to him and ask him questions. Among people are those who speak without seeing any reason to say, "I do not know" or "I am not aware." Rather, you find him issuing fatwas as if he has been doing so for years by nature; he issues fatwas on what he does not know and does not care. This is a mistake.
This is a known fact. Therefore, I say that whoever positions himself for da'wah to Allah the Exalted should devote more of his efforts to knowledge, so that his speech is based on knowledge, and when questions are directed to him, he answers based on knowledge.
