Al-Adab Al-Mufrad, Book 42, Hadith 1014 (English) ⓘ
Abu Hurayra reported that the Messenger of Allah, may Allah bless him and grant him peace, forbade people to sit in courtyards and roads. The Muslims said, "We will not be able to avoid it. We cannot undertake it." He said, "If not, then give it its due." They said, "What is it due?" He said, "Lower the eye, guide the traveller, wish for mercy on the person who sneezes when he praises Allah and return the greeting."
حَدَّثَنَا مُسَدَّدٌ، قَالَ: حَدَّثَنَا يَزِيدُ بْنُ زُرَيْعٍ، قَالَ: حَدَّثَنَا عَبْدُ الرَّحْمَنِ، عَنْ سَعِيدِ بْنِ أَبِي سَعِيدٍ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ رَسُولَ اللهِ صلى الله عليه وسلم نَهَى عَنِ الأَفْنِيَةِ وَالصُّعُدَاتِ أَنْ يُجْلَسَ فِيهَا، فَقَالَ الْمُسْلِمُونَ: لاَ نَسْتَطِيعُهُ، لاَ نُطِيقُهُ، قَالَ: أَمَّا لاَ، فَأَعْطُوا حَقَّهَا، قَالُوا: وَمَا حَقُّهَا؟ قَالَ: غَضُّ الْبَصَرِ، وَإِرْشَادُ ابْنِ السَّبِيلِ، وَتَشْمِيتُ الْعَاطِسِ إِذَا حَمِدَ اللَّهَ، وَرَدُّ التَّحِيَّةِ.
