Narrated Shu'bah: "From Abu Ishaq, from Al-Bara - and he did not hear it from him - the Messenger of Allah passed by some people from the Ansar while they were sitting in the road. He said: 'If you people must do this, then return the Salam, assist the wronged, and give directions to the one who is on the route."
حَدَّثَنَا مَحْمُودُ بْنُ غَيْلاَنَ، حَدَّثَنَا أَبُو دَاوُدَ، حَدَّثَنَا شُعْبَةُ، عَنْ أَبِي إِسْحَاقَ، عَنِ الْبَرَاءِ، وَلَمْ يَسْمَعْهُ مِنْهُ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم مَرَّ بِنَاسٍ مِنَ الأَنْصَارِ وَهُمْ جُلُوسٌ فِي الطَّرِيقِ فَقَالَ " إِنْ كُنْتُمْ لاَ بُدَّ فَاعِلِينَ فَرُدُّوا السَّلاَمَ وَأَعِينُوا الْمَظْلُومَ وَاهْدُوا السَّبِيلَ " . وَفِي الْبَابِ عَنْ أَبِي هُرَيْرَةَ وَأَبِي شُرَيْحٍ الْخُزَاعِيِّ . قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ غَرِيبٌ .
