The Prohibition of Narrating Everything One Hears Sahih Muslim Introduction 12
Arabic hadith text
وَحَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، قَالَ سَمِعْتُ عَبْدَ الرَّحْمَنِ بْنَ مَهْدِيٍّ، يَقُولُ لاَ يَكُونُ الرَّجُلُ إِمَامًا يُقْتَدَى بِهِ حَتَّى يُمْسِكَ عَنْ بَعْضِ مَا سَمِعَ .
Translation
Muhammad bin ul-Muthannā narrated to us, he said I heard Abd ar-Rahman bin Mahdī saying
‘A man cannot be an Imām whose example is followed until he withholds from some of what he hears’.
