Speak truthfully and not lie or spread false information about anyone. Respect prophets.

This hadith warns us against lying about the Prophet Muhammad (peace be upon him). It is narrated from 'Abdur-Rahman bin 'Abdullah bin Mas'ud that his father said that the Messenger of Allah said that whoever tells lies about him deliberately will take his place in Hell. This means that lying about the prophet is a major sin and those who do it will face severe punishment in the hereafter. We should always strive to speak truthfully and not lie or spread false information about anyone, especially our beloved prophet.
