It Is Dislikes To Face The Qiblah While Relieving Oneself Sunan Abi Dawud 11

Arabic hadith text
حَدَّثَنَا مُحَمَّدُ بْنُ يَحْيَى بْنِ فَارِسٍ، حَدَّثَنَا صَفْوَانُ بْنُ عِيسَى، عَنِ الْحَسَنِ بْنِ ذَكْوَانَ، عَنْ مَرْوَانَ الأَصْفَرِ، قَالَ رَأَيْتُ ابْنَ عُمَرَ أَنَاخَ رَاحِلَتَهُ مُسْتَقْبِلَ الْقِبْلَةِ ثُمَّ جَلَسَ يَبُولُ إِلَيْهَا فَقُلْتُ يَا أَبَا عَبْدِ الرَّحْمَنِ أَلَيْسَ قَدْ نُهِيَ عَنْ هَذَا قَالَ بَلَى إِنَّمَانُهِيَ عَنْ ذَلِكَ فِي الْفَضَاءِ فَإِذَا كَانَ بَيْنَكَ وَبَيْنَ الْقِبْلَةِ شَىْءٌ يَسْتُرُكَ فَلاَ بَأْسَ ‏.‏

Marwan al-Asfar said

Muhammad ibn Yahya ibn Faris narrated to us: Safwan ibn 'Isa narrated to us, from al-Hasan ibn Dhakwan, from Marwan al-Asfar, who said: I saw Ibn 'Umar make his riding beast kneel facing the Qiblah, then he sat urinating towards it. So I said, "O Abu 'Abd al-Rahman, has this not been forbidden?" He said, "Yes, indeed, that was only forbidden in open spaces. But when there is something between you and the Qiblah that conceals you, there is no harm."
