Hadith 4823
وَعَنْ حُذَيْفَةَ قَالَ: سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ: «لَا يَدْخُلُ الْجَنَّةَ قَتَّاتٌ» . مُتَّفَقٌ عَلَيْهِ. وَفِي رِوَايَةِ مُسْلِمٍ: «نَمَّامٌ»
Hudhaifah (may Allah be pleased with him) reports: I heard the Messenger of Allah (peace and blessings of Allah be upon him) say: "The tale-bearer will not enter Paradise." And in the narration of Muslim, the word used is Nammam ("tale-bearer"). Agreed upon.
