Is it a condition for the one who desires to invite to Allāh ﷻ that he should have a tazkiyah (commendation) from the people of knowledge?

Shaykh ʿAbd al-Muḥsin al-ʿAbbād al-Badr:

It is not desirable for a person that he proceeds upon speech (for the people) except that he possesses knowledge, but it is not binding that he has a tazkiyah (commendation)…It is not binding that he has a tazkiyah. However, when his affair is unknown (majhūl) and he, meaning, the people are not satisfied regarding him and wish to know (about him) whilst he is unknown to them, and they wish to know about him through the route of known people, one who brings something, making clear that he is fit (for daʿwah) and he can be benefited from, meaning there is, meaning…otherwise when this person has ability and he has grounding, and there is nothing cautionary from him, then it is permissible, even if he does not have a tazkiyah, and every one who has something of knowledge he can bring it (forth), and the Messenger said, “Convey from me, even if a (single) verse.” Yes.


He says in the completion of the question: And when is it not a condition that he has a tazkiyah and how can we know that a caller is fit for giving daʿwah especially when he did not study at the hands of the scholars?

Shaykh ʿAbd al-Muḥsin al-ʿAbbād al-Badr:

When a person is unknown (altogether), then his matter is withheld from (out of caution) and when he is known that he is known for his benefit, whether it is known that he studied and he has lessons and he has capabilities, and a person could have acquired this through habitual study, and specific lessons. It is not binding that a person should have a shahādah, meaning graduation from a faculty or that he has accompanied a Shaykh for a long period. Whoever has something of knowledge and his grounded in it, even if it was a benefit he took from a scholar, then he conveys it to others.
