The Ruling on Narrating by Meaning and What Its Authenticity Is Not Known

Question:
If a student of knowledge does not know about the authenticity of the hadith?

Answer:
He says: It is narrated, it is mentioned from him, he does not assert, it is narrated and mentioned, and he does not assert until he knows; it is forbidden for him to assert.
Q: Even if he knows that the scholars differ on it?
The Shaykh: Al-Hafiz al-Iraqi says:
And if you wish to quote a weak one, or one
in which there is doubt, not by their chains,
then use a softening like (it is narrated) and assert
the transmission of what is authentic like (he said), so know.
And this is the well-known position among the people of knowledge, and he said:
And they made it easy in the case of a non-fabricated one, they narrated
without specifying its weakness, and they saw
its specification in the ruling and the creed
from (Ibn Mahdi) and more than one person.
A person exerts effort in what concerns the evidence for prohibition and obligation, but as for admonition and reminding, the matter is broader; he does not assert, it is narrated from him that he said such and such, it is mentioned from the Messenger of Allah (peace and blessings be upon him) that he said such and such, he encourages them to good deeds.
Q: And narrating by meaning?
The Shaykh: For the people of knowledge is not for everyone, for the people of knowledge, if he is from the people of knowledge; there is no harm, if he is from the people of knowledge who knows the meanings; there is no harm.
