HAKIM 368:
from ʿUbaydullāh b. Abū Rāfiʿ from his father —
[Machine] From the Prophet ﷺ , he said: "I do not trust anyone of you while reclining on his couch, when something from my commands or prohibitions comes to him and he says, 'We do not know what we found in the Book of Allah, so we followed it.'" Sufyan ibn 'Uyaynah has established this chain and it is authentic according to the conditions of both al-Bukhari and Muslim, but they did not include it. As for me, they left it due to the disagreement of the Egyptians regarding this chain according to their conditions and they left it.
الحاكم ٣٦٨:
عن عبيد الله بن ابو رافع عن أبيه —
عَنِ النَّبِيِّ ﷺ قَالَ لَا أُلْفِيَنَّ أَحَدَكُمْ مُتَّكِئًا عَلَى أَرِيكَتِهِ يَأْتِيهِ الْأَمْرُ مِنْ أَمْرِي مِمَّا أَمَرْتُ بِهِ أَوْ نَهَيْتُ عَنْهُ فَيَقُولُ مَا أَدْرِي مَا وَجَدْنَا فِي كِتَابِ اللَّهِ اتَّبَعْنَاهُ «» قَدْ أَقَامَ سُفْيَانُ بْنُ عُيَيْنَةَ هَذَا الْإِسْنَادَ وَهُوَ صَحِيحٌ عَلَى شَرْطِ الشَّيْخَيْنِ وَلَمْ يُخَرِّجَاهُ وَالَّذِي عِنْدِي أَنَّهُمَا تَرَكَاهُ لِاخْتِلَافِ الْمِصْرِيِّينَ فِي هَذَا الْإِسْنَادِ على شرطهما وتركاه
