Jami` at-Tirmidhi, Volume 5, Book 39, Hadith 2657 (DarusSalam) ⓘ
Narrated Simak bin Hard: "I heard 'Abdur-Rahman bin 'Abdullah bin Mas'ud narrating from his father who said: 'I heard the Messenger of Allah saying: 'May Allah gladden a man who hears something from us, so he conveys it as he heard it. Perhaps the one it is conveyed to is more understanding than the one who heard it.'"
حَدَّثَنَا مَحْمُودُ بْنُ غَيْلاَنَ، حَدَّثَنَا أَبُو دَاوُدَ، أَنْبَأَنَا شُعْبَةُ، عَنْ سِمَاكِ بْنِ حَرْبٍ، قَالَ سَمِعْتُ عَبْدَ الرَّحْمَنِ بْنَ عَبْدِ اللَّهِ بْنِ مَسْعُودٍ، يُحَدِّثُ عَنْ أَبِيهِ، قَالَ قَالَ سَمِعْتُ النَّبِيَّ صلى الله عليه وسلم يَقُولُ " نَضَّرَ اللَّهُ امْرَأً سَمِعَ مِنَّا شَيْئًا فَبَلَّغَهُ كَمَا سَمِعَ فَرُبَّ مُبَلَّغٍ أَوْعَى مِنْ سَامِعٍ " . قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ وَقَدْ رَوَاهُ عَبْدُ الْمَلِكِ بْنُ عُمَيْرٍ عَنْ عَبْدِ الرَّحْمَنِ بْنِ عَبْدِ اللَّهِ .
