The reason for the claim that there is a discrepancy in the hadith "There is no harm and no reciprocating harm"

Question:
Honorable Shaykh, regarding the hadith "There is no harm and no reciprocating harm," you stated that there is discussion about it. How can there be discussion when Imam Ahmad, who is one of the hadith scholars, narrated it, as did Ibn Majah? I hope you will clarify this.

Answer:
And the authors of the Sunan did not commit to writing only authentic hadiths in their books. Those who started this practice, such as al-Bukhari, Muslim, Ibn Khuzaymah, and Ibn Hibban, are the exception. In fact, they include authentic, good, and weak hadiths in their works, but they do not include fabricated ones. They mention the chain of narration from beginning to end, so people know the chain and the narrators in it, and they know its ruling. They find its context from the chain; it may be weak even if the Imam narrated it, it may be weak even if the Imam narrated it, even if the Imam narrated it, because those other than the authors of the authentic collections did not commit to narrating only authentic hadiths. Rather, they write by mentioning the chain, and the scholars know the chain of this hadith: is it authentic or not?
