Abu Sa`id al-Khudri reported the Messenger of Allah ﷺ as saying :
Avoid sitting in the roads. The people said: Apostle of Allah! We must have meeting places in which to converse. The apostle of Allah ﷺ said: If you insist on meeting, give the road its due. They asked: What is the due of roads, Apostle of Allah? He replied: Lowering the eyes, removing anything offensive, returning salutation, commanding what is reputable and forbidding what is disreputable.

حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مَسْلَمَةَ، حَدَّثَنَا عَبْدُ الْعَزِيزِ، - يَعْنِي ابْنَ مُحَمَّدٍ - عَنْ زَيْدٍ، - يَعْنِي ابْنَ أَسْلَمَ - عَنْ عَطَاءِ بْنِ يَسَارٍ، عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ، أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ " إِيَّاكُمْ وَالْجُلُوسَ بِالطُّرُقَاتِ " . فَقَالُوا يَا رَسُولَ اللَّهِ مَا بُدٌّ لَنَا مِنْ مَجَالِسِنَا نَتَحَدَّثُ فِيهَا . فَقَالَ رَسُولُ اللَّهِ ﷺ " إِنْ أَبَيْتُمْ فَأَعْطُوا الطَّرِيقَ حَقَّهُ " . قَالُوا وَمَا حَقُّ الطَّرِيقِ يَا رَسُولَ اللَّهِ قَالَ " غَضُّ الْبَصَرِ وَكَفُّ الأَذَى وَرَدُّ السَّلاَمِ وَالأَمْرُ بِالْمَعْرُوفِ وَالنَّهْىُ عَنِ الْمُنْكَرِ " .
