I discussed this chapter with our Shaykh Abu Ali al-Hafiz and asked: "Is any of these chains from Ata authentic?" He said: "No." I asked: "Why?" He said: "Because Ata did not hear it from Sayyiduna Abu Hurayrah (may Allah be pleased with him)." So we received this hadith in which an unnamed man stands between Ata and Abu Hurayrah, that the Messenger of Allah (peace and blessings be upon him) said: "Whoever is asked about knowledge and conceals it, Allah will bridle him on the Day of Resurrection with a bridle of fire." I said to him: "Azhar bin Marwan or your Shaykh Ibn Ahmad al-Wasiti made an error in this, and an error from either of them is not unlikely."
