(5) باب فِي أَنَّ الإِسْنَادَ مِنَ الدِّينِ وَأَنَّ الرِّوَايَةَ لَا تَكُونُ إِلَّا عَنْ الثِّقَاتِ وَأَنَّ جَرْحَ الرُّوَاةِ بِمَا هُوَ فِيهِمْ جَائِزٌ بَلْ وَاجِبٌ وَأَنَّهُ لَيْسَ مِنْ الْغِيبَةِ الْمُحَرَّمَةِ بَلْ مِنْ الذَّبِّ عَنْ الشَّرِيعَةِ الْمُكَرَّمَةِ
Ishāq bin Ibrāhīm al-Hanthalī narrated to us, Īsā, and he is Ibn Yūnus, informed us, al-Awzā'ī narrated to us, on authority of Sulyamān bin Mūsā, he said:
'I came across Tāwus and said: 'So-and-so narrated to me such-and-such'. Then he said: 'If your companion is trustworthy, then take from him.'
