[Machine] He heard Abu Ayyub Al-Ansari say, "The Messenger of Allah ﷺ forbade us from facing or turning away from the Qiblah (direction of prayer) when one of us goes to urinate or defecate."  

الطبراني:٣٩٣٣ – حَدَّثَنَا مُحَمَّدُ بْنُ يَزْدَادَ التَّوْزِيُّ الْبَصْرِيُّ ثنا الْوَلِيدُ بْنُ شُجَاعٍ ثنا عَنْبَسَةُ بْنُ عَبْدِ الْوَاحِدِ عَنْ مُحَمَّدِ بْنِ يَعْقُوبَ عَنْ إِسْحَاقَ بْنِ عَبْدِ اللهِ أَبِي طَلْحَةَ عَنْ رَافِعِ بْنِ إِسْحَاقَ رَجُلٍ مِنْ قُدَمَاءِ أَهْلِ الْمَدِينَةِ

أَنَّهُ سَمِعَ أَبَا أَيُّوبَ الْأَنْصَارِيَّ يَقُولُ «نَهَانَا رَسُولُ اللهِ ﷺ أَنْ نَسْتَقْبِلَ الْقِبْلَةَ أَوْ نَسْتَدْبِرَهَا إِذَا ذَهَبَ أَحَدُنَا يَبُولُ أَوْ يَتَغَوَّطُ»

"The Messenger of Allah forbade the person who went to the Gha'it to face the Qiblah. He said: 'face towards the east or the west.'"  

ابن ماجة:٣١٨ – حَدَّثَنَا أَبُو الطَّاهِرِ أَحْمَدُ بْنُ عَمْرِو بْنِ السَّرْحِ أَنْبَأَنَا عَبْدُ اللَّهِ بْنُ وَهْبٍ أَخْبَرَنِي يُونُسُ عَنِ ابْنِ شِهَابٍ عَنْ عَطَاءِ بْنِ يَزِيدَ

أَنَّهُ سَمِعَ أَبَا أَيُّوبَ الأَنْصَارِيَّ يَقُولُ نَهَى رَسُولُ اللَّهِ ﷺ أَنْ يَسْتَقْبِلَ الَّذِي يَذْهَبُ إِلَى الْغَائِطِ الْقِبْلَةَ وَقَالَ شَرِّقُوا أَوْ غَرِّبُوا
