(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
Nasr bin Alī al-Jahdhamī narrated to us, al-Asma'ī narrated to us, on authority of Ibn Abī-Zinād, on authority of his father, he said:
'I met one hundred [transmitters] in al-Madīnah, each of whom were reliable. Narrations were not taken from one about who it was said, 'he is not from its people'.'
