Some well-known lines fall below those generally treated as the strongest sahih chains, while their individual reports can still qualify as hasan when the relevant conditions are satisfied.
«كَمُحَمَّدِ بْنِ إِسْحَاقَ، عَنْ عَاصِمِ بْنِ عُمَرَ، عَنْ جَابِرٍ»
For example, Muhammad ibn Ishaq from ʿAsim ibn ʿUmar, from Jabir.
«وَعَمْرِو بْنِ شُعَيْبٍ، عَنْ أَبِيهِ، عَنْ جَدِّهِ»
And ʿAmr ibn Shuʿayb from his father, from his grandfather.
These illustrate that named transmitters and chains do not all carry an identical evidentiary rank. The actual preservation of each report, its transmission mode, relevant links, and corroborating indications affect the final evaluation.
