The Prophet (sal Allaahu alayhi wa sallam ) as saying : Be on your guard against two things which provoke cursing. They (the hearers) said : Prophet of Allaah ( sal Allaahu alayhi wa sallam), what are these things which provoke cursing: easing in the watering places and on the thoroughfares, and in the shade (of the tree)(where they take shelter and rest).  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ اتَّقُوا اللاَّعِنَيْنِ قَالُوا وَمَا اللاَّعِنَانِ يَا رَسُولَ اللَّهِ قَالَ الَّذِي يَتَخَلَّى فِي طَرِيقِ النَّاسِ أَوْ ظِلِّهِمْ  

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).  

قَالَ رَسُولُ اللَّهِ ﷺ اتَّقُوا الْمَلاَعِنَ الثَّلاَثَ الْبَرَازَ فِي الْمَوَارِدِ وَقَارِعَةِ الطَّرِيقِ وَالظِّلِّ
