What is the opinion of one who has graduated but does not have the knowledge that qualifies him to teach in the mosques?

The questioner : Honorable Shaykh, this questioner says: Honorable Shaykh, what is your opinion of one who graduated from this university but does not have the fiqh and knowledge that qualifies him to teach in the mosques, as he sees it in himself? Is it permissible for him to teach, or is he among those who claim to be scholars?

The Shaykh : The measure for this is the saying of the Prophet (peace and blessings be upon him) So any matter of knowledge that a person knows, he is required to convey it. It is not, it is not the case that we say, nor does anyone say, that one who has knowledge. It is not permissible for a person to teach unless he has a great deal of knowledge; is that correct?
I am giving you an example, and I do not want to justify absolutely what the Tabligh group does. One of the Tabligh group comes, and he is among the most beautiful of Allah’s servants, but he has some texts of promise or threat or warning and intimidation. Then he stands in a mosque and speaks, and he has a profound effect, even though they have a great deal of ignorance that is well known. And yet they have an effect. Yes, a person does not speak except with what he knows, meaning he does not speak with everything he hears of hadiths of encouragement and warning, because many of the hadiths of encouragement and warning have some issues, and some are fabricated. But I say: strive to benefit the people, even if it is with a little, except that you do not speak except with what you know.

The presenter : Yes, may Allah bless you,
