It is narrated from Abdullah bin Shaqiq that he said: I sat with a group of people, of whom I was the fourth. One of them said: I heard the Messenger of Allah (peace and blessings be upon him) say: "Through the intercession of one man of my Ummah, more people than (the tribe of) Banu Tamim will enter Paradise." We said: (O Messenger of Allah!) Someone other than you? He (peace and blessings be upon him) said: "Yes, someone other than me." I (Abdullah bin Shaqiq) asked: Did you yourself hear this from the Messenger of Allah (peace and blessings be upon him)? He replied: Yes. When that man left, I asked: Who was this? The people said: This was Ibn Abi al-Jad'a' (a Companion of the Messenger of Allah). This hadith is sahih, and Bukhari and Muslim used its narrators as evidence. Abdullah bin Shaqiq is a Tabi'i who is used as evidence. The two of them (the two Shaykhs) left it out only because, as we mentioned earlier, a single Tabi'i is alone in narrating from a Companion (which was against their standard).
