«وَمِنْهَا الْمَشْهُورُ إِذَا كَانَتْ لَهُ طُرُقٌ مُتَبَايِنَةٌ سَالِمَةٌ مِنْ ضَعْفِ الرُّوَاةِ وَالْعِلَلِ»
The second case is a mashhur report with genuinely distinct transmission routes free from narrator weakness and effective hidden defects.
Diverse routes are not simply numerous later pupils reproducing a single earlier source. The multiplicity must provide real independent support. Freedom from weakness and defects requires investigating the transmitters' reliability and precision and any concealed flaw affecting the report.
Consequently, listing three or four chains is not enough to claim that this type yields knowledge. The independence and critical soundness of the routes are essential elements of the argument.
