وَحَدَّثَنِي الْفَضْلُ بْنُ سَهْلٍ، حَدَّثَنَا وَلِيدُ بْنُ صَالِحٍ، قَالَ: قَالَ عُبَيْدُ اللَّهِ بْنُ عَمْرٍو: قَالَ زَيْدٌ، يَعْنِي ابْنَ أَبِي أُنَيْسَةَ: لَا تَأْخُذُوا عَنْ أَخِي.
Translation: Al-Faḍl b. Sahl reports through Walīd b. Ṣāliḥ that ʿUbayd Allāh b. ʿAmr transmitted Zayd b. Abī Unaysah’s warning: “Do not take reports from my brother.”
“My brother” establishes a family relationship, not reliability in transmission. Close kinship cannot substitute for evidence about how someone narrates.
