Route one: Abū Bakr ibn Abī Shaybah → Wakīʿ → Shuʿbah → al-Ḥakam → ʿAbd al-Raḥmān ibn Abī Laylā → Samurah.
Route two: Abū Bakr ibn Abī Shaybah → Wakīʿ → Shuʿbah and Sufyān → Ḥabīb → Maymūn ibn Abī Shabīb → al-Mughīrah.
The first two transmitters overlap, but the remaining portions constitute distinct Companion routes. In route two, Wakīʿ reports the Ḥabīb transmission through Shuʿbah and Sufyān as parallel authorities, not as consecutive links. Comparison helps study corroboration and variation; the presence of two chains does not automatically prove every transmitter’s accuracy or every claimed encounter.
Al-Nawawī identifies two specific laṭāʾif al-isnād in these very chains:
(1) Geographical pattern: he classifies their transmitters as Kūfan, with the exception of Shuʿbah ibn al-Ḥajjāj, who is described as Wāsiṭī and subsequently Baṣran. This is an observation about transmitters’ regional associations, not an automatic authentication criterion.
(2) A Successor narrating from another Successor occurs in each chain: al-Ḥakam ibn ʿUtaybah → ʿAbd al-Raḥmān ibn Abī Laylā in the first, and Ḥabīb ibn Abī Thābit → Maymūn ibn Abī Shabīb in the second. Thus isnād analysis examines generational nesting, not simply the number of links before the Companion.
