فَأَمَّا مَنْ تَرَاهُ يَعْمِدُ لِمِثْلِ الزُّهْرِيِّ فِي جَلَالَتِهِ وَكَثْرَةِ أَصْحَابِهِ الْحُفَّاظِ الْمُتْقِنِينَ لِحَدِيثِهِ وَحَدِيثِ غَيْرِهِ، أَوْ لِمِثْلِ هِشَامِ بْنِ عُرْوَةَ
Translation: By contrast, consider someone reporting from an eminent teacher such as al-Zuhrī, with numerous precise pupils, or Hishām b. ʿUrwah.
Many of these teachers’ reports were well known and transmitted by skilled companions. There is therefore ample comparative evidence. A person claiming unusual material from such a source requires scrutiny in light of the established corpus and the person’s own participation in it.
