ذِكْرُ الزَّجْرِ عَنِ الِاسْتِطَابَةِ بِالرَّوْثِ وَالْعَظْمِ
The Apostle of Allaah ( sal Allaahu alayhi wa sallam ) as saying: I am like father to you. When any of you goes to privy, he should not face or turn his back towards the qiblah. He should not cleanse with his right hand. He (the Prophet, sal Allaahu alayhi wa sallam) also commanded the Muslims to use three stones and forbade them to use dung or decayed bone. (Using translation from Abū Dāʾūd 8)
قَالَ رَسُولُ اللَّهِ ﷺ «إِنِّي أَنَا لَكُمْ مِثْلُ الْوَالِدِ أُعَلِّمُكُمْ إِذَا أَتَيْتُمُ الْغَائِطَ فَلَا تَسْتَقْبِلُوا الْقِبْلَةَ وَلَا تَسْتَدْبِرُوهَا وَلَا يَسْتَنْجِ أَحَدُكُمْ بِيَمِينِهِ» وَكَانَ يَأْمُرُ بِثَلَاثَةِ أَحْجَارٍ وَيَنْهَى عَنِ الرَّوْثَةِ وَالرِّمَّةِ
