The Prophet ﷺ said, "It is enough sin for a person to repeat everything he hears."
حدثنا حفص بن عمر حدثنا شعبة ح و حدثنا محمد بن الحسين حدثنا علي بن حفص قال حدثنا شعبة عن خبيب بن عبد الرحمن عن حفص بن عاصم قال ابن حسين في حديثه
أن النبي ﷺ قال كفى بالمرء إثما أن يحدث بكل ما سمع
Muslim narrated it, in the Introduction, chapter on the prohibition of reporting everything one hears, hadith no. 5, from the hadith of Ali bin Hafs, through this route, and he alone narrated it, as Abu Dawud and others said. In some copies of Sahih Muslim there appears an error made by the copyists, and some scholars used it to refute Abu Dawud, may Allah have mercy on him, but this refutation is itself rejected. See the Indian copies of Sahih Muslim to verify what is correct.
