835 - Ahmad ibn 'Ali al-Abbar said: I asked Sufyan ibn Waki', and I said: "Should we write down these poor-quality hadiths?" He replied: "No person has ever sought them and found success." He (al-Abbar) said: "I asked Abu Hammam, and he said: 'Do not write them down.' And I asked Mujahid ibn Musa, and he said: 'Why would you write them down?' I replied: 'So that we may recognize them.' He said: 'You recognize evil.'"
