"The Prophet prohibited us from facing the Qiblah while urinating. Then i saw him facing it a year before he died."  

نَهَى النَّبِيُّ ﷺ أَنْ نَسْتَقْبِلَ الْقِبْلَةَ بِبَوْلٍ فَرَأَيْتُهُ قَبْلَ أَنْ يُقْبَضَ بِعَامٍ يَسْتَقْبِلُهَا وَفِي الْبَابِ عَنْ أَبِي قَتَادَةَ وَعَائِشَةَ وَعَمَّارِ بْنِ يَاسِرٍ  

he saw the Prophet urinating while facing the Qiblah. Qutaibah narrated that to us, he said: "Ibn Lahi'ah informed us." Jabir's Hadlth about the Prophet is more correct than the Hadith of Ibn Lahi'ah. Ibn Lahi'ah is weak according to the scholars of Hadith. He was graded weak by Yahya bin Sa'eed Al-Qattan, and others, [due to his memorization].  

أَنَّهُ رَأَى النَّبِيَّ ﷺ يَبُولُ مُسْتَقْبِلَ الْقِبْلَةِ حَدَّثَنَا بِذَلِكَ قُتَيْبَةُ حَدَّثَنَا ابْنُ لَهِيعَةَ وَحَدِيثُ جَابِرٍ عَنِ النَّبِيِّ ﷺ أَصَحُّ مِنْ حَدِيثِ ابْنِ لَهِيعَةَ وَابْنُ لَهِيعَةَ ضَعِيفٌ عِنْدَ أَهْلِ الْحَدِيثِ ضَعَّفَهُ يَحْيَى بْنُ سَعِيدٍ الْقَطَّانُ وَغَيْرُهُ مِنْ قِبَلِ حِفْظِهِ  

"One day I climbed on Hafsah's house, and I saw the Prophet relieving himself while facing Ash-Sham, with his back toward the Ka'bah."  

رَقِيتُ يَوْمًا عَلَى بَيْتِ حَفْصَةَ فَرَأَيْتُ النَّبِيَّ ﷺ عَلَى حَاجَتِهِ مُسْتَقْبِلَ الشَّأْمِ مُسْتَدْبِرَ الْكَعْبَةِ
