عَنْ أَبِي شُرَيْحِ بْنِ عَمْرٍو الْخُزَاعِيِّ رَضِيَ اللَّهُ عَنْهُ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ إِيَّاكُمْ وَالْجُلُوسَ عَلَى الصُّعُدَاتِ فَمَنْ جَلَسَ مِنْكُمْ عَلَى الصَّعِيدِ فَلْيُعْطِهِ حَقَّهُ قَالَ قُلْنَا يَا رَسُولَ اللَّهِ وَمَا حَقُّهُ قَالَ غَضُّ الْبَصَرِ وَرَدُّ التَّحِيَّةِ وَأَمْرٌ بِمَعْرُوفٍ وَنَهْيٌ عَنْ مُنْكَرٍ
Sayyiduna Abu Shurayh bin Amr Khuzai (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: Avoid sitting on the roads. If someone wishes to sit on the road, then he should fulfill its right. We said: O Messenger of Allah! What is the right of the road? He (peace and blessings be upon him) said: Lowering the gaze, responding to greetings, enjoining good, and forbidding evil.
