Machine translationRead the Arabic original
Question : The questioner asks: What is the authenticity of the hadith, or rather, what is its meaning?
Answer : No, "there is no backbiting of an open sinner"—this is not a hadith, it is not authentic, and its meaning is not authentic either. For the open sinner exits from Islam, and Allah the Exalted said:[Al-Hujurat 49:12] However, punishing the open sinner for his open sinfulness and warning people against him is a necessity. As for speaking about the honor of the open sinner, this is not permissible because he is a believer, and Allah the Exalted said: "Nor should you backbite one another."
Answer : No, "there is no backbiting of an open sinner"—this is not a hadith, it is not authentic, and its meaning is not authentic either. For the open sinner exits from Islam, and Allah the Exalted said:
or backbite each other
وَلَا يَغْتَب بَّعْضُكُم بَعْضًا
