وَعَنْ مُعَاذٍ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: اتَّقُوا الْمَلَاعِنَ الثَّلَاثَةَ: الْبَرَازَ فِي الْمَوَارِدِ وَقَارِعَةِ الطَّرِيقِ وَالظِّلِّ . رَوَاهُ أَبُو دَاوُد وَابْن مَاجَه
Mu'adh reported God's messenger as saying, "Guard against the three things which produce cursing:relieving oneself in watering-places, in the middle of the road, and in the shade.” Abu Dawud and Ibn Majah transmitted it.
