سنن أبي داود#26Hasanحَدَّثَنَا إِسْحَاقُ بْنُ سُوَيْدٍ الرَّمْلِيُّ، وَعُمَرُ بْنُ الْخَطَّابِ أَبُو حَفْصٍ، وَحَدِيثُهُ، أَتَمُّ أَنَّ سَعِيدَ بْنَ الْحَكَمِ، حَدَّثَهُمْ قَالَ أَخْبَرَنَا نَافِعُ بْنُ يَزِيدَ، حَدَّثَنِي حَيْوَةُ بْنُ شُرَيْحٍ، أَنَّ أَبَا سَعِيدٍ الْحِمْيَرِيَّ، حَدَّثَهُ عَنْ مُعَاذِ بْنِ جَبَلٍ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " اتَّقُوا الْمَلاَعِنَ الثَّلاَثَ الْبَرَازَ فِي الْمَوَارِدِ وَقَارِعَةِ الطَّرِيقِ وَالظِّلِّ " .
Narrated Mu'adh ibn Jabal: The Messenger of Allah (ﷺ) said: Be on your guard against three things which provoke cursing: easing in the watering places and on the thoroughfares, and in the shade (of the tree)
