What is the authenticity of the hadith (Part of a person's good Islam is that he leaves what does not concern him), and what is the understanding of this hadith?

The questioner : If this hadith is authentic, then its understanding becomes clear to us; may Allah reward you with good.

The Shaykh : As for the well-known hadith , it is, praise be to Allah, an authentic hadith, and it contains a high level of proper conduct, which is that a person should not interfere in what does not concern him from the affairs of others; that a Muslim should not interfere in what does not concern him from the affairs of other Muslims, meaning he should not interfere in a person's private matters. But this does not mean that he should not advise him or mention it to him if he sees him committing an error; in that case, his affair does concern him, so we must distinguish between private matters related to a person; here, a Muslim should not interfere in his private affairs. However, if a Muslim falls into an error, then the Muslim who sees this error should take an interest in it and remind him of his error, but in the best manner, as is the Qur'anic rule . And naturally, if we know this distinction, if we see people innovating in worship with no basis in the Book of Allah or in the hadith of the Messenger of Allah (peace and blessings be upon him), and we advise them and remind them with his saying (peace be upon him): and with his saying (peace be upon him) in the well-known hadith: , then this has no relation to the first hadith because this falls under his saying (peace be upon him): . This is what can be said in answer to this question.
