Explanation

The meaning in a few plain lines

The Prophet (may Allah's peace and blessings be upon him) commands us to convey knowledge from him, from the Qur’an or the Sunnah, even if it is something short, like a verse from the Qur’an or a Hadīth, provided that a person should have knowledge of what he conveys and invites people to it. Then, the Prophet (may Allah's peace and blessings be upon him) points out that there is no sin in narrating about the Children of Israel and the events that happened to them, in a way that does not run counter to our Shariah. Then, he warns against telling lies about him and states that whoever intentionally lies about him should occupy his dwelling in Hellfire.
