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
'Abd al-Rahman ibn Mahdi said, “A man cannot be a leader whose example is followed until he refrains from repeating some of what he hears.”
