Sayyiduna Sa'd bin Abi Waqqas (may Allah be pleased with him) narrates: At "al-Nabawah" (the narrator is unsure, or perhaps the words are: at the place "al-Naba'ah") I heard the Prophet (peace and blessings be upon him) say: "Soon the people of Paradise will be recognised from the people of Hell." The people said: "O Messenger of Allah! How?" The Prophet (peace and blessings be upon him) said: "Through good praise or bad praise."
Imam al-Bazzar recorded this narration, and its narrators are the narrators of the Sahih, except for al-Hasan bin Arafah, who is thiqah (trustworthy).
