Sahih Muslim , Hadith 269 ⓘ
Abu Huraira reported: The Messenger of Allah said: Be on your guard against two things which provoke cursing. They (the companions present there) said: Messenger of Allah, what are those things which provoke cursing? He said: Easing on the thoroughfares or under the shades (where they take shelter and rest).
حَدَّثَنَا يَحْيَى بْنُ أَيُّوبَ، وَقُتَيْبَةُ، وَابْنُ، حُجْرٍ جَمِيعًا عَنْ إِسْمَاعِيلَ بْنِ جَعْفَرٍ، - قَالَ ابْنُ أَيُّوبَ حَدَّثَنَا إِسْمَاعِيلُ، - أَخْبَرَنِي الْعَلاَءُ، عَنْ أَبِيهِ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " اتَّقُوا اللَّعَّانَيْنِ " . قَالُوا وَمَا اللَّعَّانَانِ يَا رَسُولَ اللَّهِ قَالَ " الَّذِي يَتَخَلَّى فِي طَرِيقِ النَّاسِ أَوْ فِي ظِلِّهِمْ " .
