«وَالْمُتَوَاتِرُ لَا يُبْحَثُ عَنْ رِجَالِهِ، بَلْ يَجِبُ الْعَمَلُ بِهِ مِنْ غَيْرِ بَحْثٍ»
For the mutawatir report, individual transmitter criticism is not required in the same way; its established status obliges acceptance without that separate inquiry.
This does not mean that an unsupported claim of tawatur should be accepted. The existence of its conditions must first be established: sufficient routes, persistence through the levels, sensory origin, and certain knowledge.
Once those are verified, certainty rests on the cumulative transmission rather than merely on one narrator's personal reliability. Ahad reports, in contrast, require more direct attention to transmitter reliability, precision, continuity, and related questions.
