What is your opinion of the one who says, "Do not engage in da'wah (calling others to Islam) until you are a great student of knowledge"?

The questioner : Your Eminence the Shaykh! What is your opinion of the one who says, "Do not engage in da'wah until you are a great student of knowledge"? And we, praise be to Allah, have what we speak to people with, and what qualifies us to engage in da'wah, knowing that the Messenger (peace and blessings be upon him) said, "Convey from me even if it is one verse." The hadith.

The Shaykh : I believe the questioner has answered himself with the words of one who is better than me, and who is that? The Messenger (peace and blessings be upon him), who said And a person is commanded to convey what he knows of the Shari'ah (Islamic sacred law), even if it is little. But he must beware of making himself a great mufti (a scholar who issues fatwas), because some people, when they speak a sermon and then the attendees stand up and ask him questions, he issues rulings on what is correct and what is incorrect. And his soul tells him, "If you say 'I do not know,' your status will drop in the eyes of the people." And this, by Allah, is a mistake.
If a person says regarding what he does not know, "I do not know," then his status among the people rises, just as his status with Allah rises. Allah Blessed and Exalted is He said: Listen, O brothers. Who knows? "Do not follow what you have no knowledge of." Correct level. This is a recent hadith. . If you hit close. Taqfu is derived from al-qafa (the back of the head). And whoever walks behind another is following him, meaning do not follow what you have no knowledge of, in speech or in submission.
In speech or in submission And Allah the Exalted said: . So if a person says regarding what he does not know, "I do not know," then this, by Allah, is knowledge and it is faith. And at that time, the people’s trust in him increases, and they respect him and honor him. But if he does not scrupulously refrain, and whenever he is asked about something he says "so and so," then this is a mistake. And our Shaykh (may Allah have mercy on him) related to us, in the time of seeking knowledge, a story about Ibn Jinni. And Ibn Jinni was a scholar among the scholars of grammar and intelligent. And he had a father. He pretended to be a learned Shaykh, so people would ask him, they would ask his father, and he had no knowledge, and he would stand confused. It is said that his son said to him, "O my father, whenever someone asks you about an issue, say in it, 'There are two opinions,' there are two opinions." For example, "Is this haram (forbidden) or halal (lawful)?" He said, "There are two opinions," meaning one opinion says it is halal and one opinion says it is haram. So a man came and said to him, "What do you say regarding the word of Allah the Exalted? 'Is there any doubt in Allah?'" He said, "There are two opinions." "Is there any doubt in Allah?" He said, "There are two opinions." Then he referred him to his son, saying, "My son will explain the two opinions." How do you interpret this? Strange, O people, especially the students of Arabic. "Is there any doubt in Allah?" There are two opinions? Where are the students of Arabic? Are they shy or not? I told you in my first speech that frankness is the best thing. No one knows? He said, "Two opinions" in its grammatical parsing. Is "shak" (doubt) the subject of the hidden pronoun? Is it in the verse "Is there any doubt in Allah?" Or is it a subject and the predicate is the prepositional phrase that precedes it?
He graduated, so the "two opinions" were about what? About the existence of Allah, or about the grammatical parsing of the verse? About the grammatical parsing of the verse. So I say, may Allah bless you, some people rush into issuing fatwas. And they say, "This is halal and this is haram," and if he is scrupulous, he says, "By Allah, this and that are both possible." Yes. It is not permissible for a person to proceed to issuing a fatwa unless he sees that this is the Shari'ah of Allah the Mighty and Majestic.
