Ubayd Allah bin Mu’ādh al-Anbarī narrated to me, my father narrated to us, he said:
‘I wrote to Shu’bah asking him about Abū Shaybah , a judge of Wāsit, so he wrote to me: ‘Do not write anything from him [of Ḥadīth] and tear up my letter [to you about this]’.

حَدَّثَنِي عُبَيْدُ اللَّهِ بْنُ مُعَاذٍ الْعَنْبَرِيُّ، حَدَّثَنَا أَبِي قَالَ، كَتَبْتُ إِلَى شُعْبَةَ أَسْأَلُهُ عَنْ أَبِي شَيْبَةَ، قَاضِي وَاسِطٍ فَكَتَبَ إِلَىَّ لاَ تَكْتُبْ عَنْهُ شَيْئًا وَمَزِّقْ كِتَابِي .
