وَحَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، قَالَ: سَمِعْتُ عَبْدَ الرَّحْمَنِ بْنَ مَهْدِيٍّ، يَقُولُ: «لَا يَكُونُ الرَّجُلُ إِمَامًا يُقْتَدَى بِهِ حَتَّى يُمْسِكَ عَنْ بَعْضِ مَا سَمِعَ».
Translation: Muḥammad b. al-Muthannā said he heard ʿAbd al-Raḥmān b. Mahdī say: A person cannot become a followed authority until he refrains from transmitting some of what he hears.
“Yumsik” requires withholding some reports; it is not a mandate to suppress established religious guidance. Accumulating material and discriminating what responsibly deserves narration are two different scholarly skills.
