Speak truthfully and kindly when talking about others; Avoid exaggerating their qualities or accomplishments; Strive for moderation in speech.

This hadith is about the harm of excessive praise. It was narrated by Abu Musa, who reported that Allah's Messenger saw a person praising another person too much. In response, the Prophet said that this kind of excessive praise can be as harmful as killing or slicing someone's back. This hadith teaches us to be careful with our words and not to overpraise someone, as it can have negative consequences for both parties involved. We should always strive to speak truthfully and kindly when talking about others, and avoid exaggerating their qualities or accomplishments in order to protect them from potential harm.
