وَعَنْ سُرَاقَةَ بْنِ مَالِكٍ - رضى الله عنه - قَالَ: { عَلَّمْنَا رَسُولُ اَللَّهِ - صلى الله عليه وسلم -فِي اَلْخَلَاءِ: أَنَّ نَقْعُدَ عَلَى اَلْيُسْرَى, وَنَنْصِبَ اَلْيُمْنَى } رَوَاهُ اَلْبَيْهَقِيُّ بِسَنَدٍ ضَعِيف ٍ [1] .
Narrated Suraqa bin Malik (rad): Allah’s Messenger (ﷺ) educated us about lavatory (manners) that we should sit on our left foot and keep erect our right foot. [Reported by Al-Baihaqi through a chain of weak narrators].
