Below the highest-ranked isnads stand other acceptable chains whose transmitters remain upright and precise but whose additional strengths are relatively less compelling.
Illustrations of the next tier:
Burayd ibn ʿAbd Allah ibn Abi Burdah → his grandfather Abu Burdah → Abu Musa al-Ashʿari.
Hammad ibn Salamah → Thabit al-Bunani → Anas ibn Malik.
Further illustrations:
Suhayl ibn Abi Salih → his father → Abu Hurayrah.
Al-ʿAlaʾ ibn ʿAbd al-Rahman → his father → Abu Hurayrah.
A relatively lower placement does not automatically classify the latter chains as weak. Their reports can still meet the conditions of acceptance, but their preservation strength and corroborating qualities are not identical. Each report's precise wording, links, and competing routes must still be evaluated.
