وَعَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ
قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: اتَّقُوا اللَّاعِنَيْنِ. قَالُوا: وَمَا اللَّاعِنَانِ يَا رَسُولَ اللَّهِ؟. قَالَ: «الَّذِي يَتَخَلَّى فِي طَرِيقِ النَّاس أَو فِي ظلهم»
The Prophet (sallallahu alayhi wa sallam) said:, “Guard against the two things which produce cursing.” He was asked what they were and said, “Relieving oneself where people walk, or where they sit in the shade.”
