What is the ruling on sending a video of commendation without verifying the authenticity of the hadiths mentioned in it? And is it considered correct to act by correcting hadiths and clarifying their weakness to a lecturer who mentions weak hadiths or in an incorrect صيغة (formulation)? What should be done in this regard, especially after reminding her of the fatwa warning against narrating weak hadiths without clarification?

The believer must verify the hadiths attributed to the Prophet, peace and blessings be upon him, for a severe warning has been issued against those who narrate falsehoods. Although scholars have permitted the narration of weak hadiths in matters of spiritual purification (tazkiyah) and admonitions, this is subject to controls and conditions. These include that the hadith (definition) should not be severely weak, and it should be narrated using a form that indicates uncertainty (such as: "It was narrated from the Messenger of Allah"), or by mentioning its isnad (definition) (chain of narration). In this era, due to people's inability to distinguish, the weakness of the hadith must be clarified. Therefore, there is no harm in disseminating spiritual purification clips from trustworthy scholars known for their knowledge. However, as for those who promote weak hadiths, one must refrain from disseminating them until the hadiths mentioned therein are verified. And cautioning those who err in hadiths is a good matter and falls under legitimate advice.
