I sat with a group of four, myself being the fourth, in Iliya. One of them said, "I heard the Messenger of Allah ﷺ say, 'More people than the tribe of Banu Tamim will enter Paradise through the intercession of a single man from my community.'"We asked, "Other than yourself, Messenger of Allah?"He said, "Other than myself."I asked, "Did you yourself hear this?"He replied, "Yes."When he stood up, I asked, "Who is this man?"They said, "He is Ibn Ubayy al-Jadaa."
