Abu Sa'id Al-Khudri reported Allah's Apostle (ﷺ) as saying:Avoid sitting on the paths. They (his Companions) said: Allah's Messenger, there is no other help to it (but to sit there as we) hold our meetings and discuss matters there. Thereupon Allah's Messenger (ﷺ) said: If you have to sit at all, then fulfil the rights, of the path. They said: What are their rights? Thereupon he said: Keeping the eye downward (so that you may not stare at the women), refraining from doing some harm to the other and exchanging mutual greetings (saying as-Salamu 'Alaikum to one another) and commanding the good and forbidding the evil.
حَدَّثَنِي سُوَيْدُ بْنُ سَعِيدٍ، حَدَّثَنِي حَفْصُ بْنُ مَيْسَرَةَ، عَنْ زَيْدِ بْنِ أَسْلَمَ، عَنْ عَطَاءِ، بْنِ يَسَارٍ عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ " إِيَّاكُمْ وَالْجُلُوسَ فِي الطُّرُقَاتِ " . قَالُوا يَا رَسُولَ اللَّهِ مَا لَنَا بُدٌّ مِنْ مَجَالِسِنَا نَتَحَدَّثُ فِيهَا . قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " فَإِذَا أَبَيْتُمْ إِلاَّ الْمَجْلِسَ فَأَعْطُوا الطَّرِيقَ حَقَّهُ " . قَالُوا وَمَا حَقُّهُ قَالَ " غَضُّ الْبَصَرِ وَكَفُّ الأَذَى وَرَدُّ السَّلاَمِ وَالأَمْرُ بِالْمَعْرُوفِ وَالنَّهْىُ عَنِ الْمُنْكَرِ " .
