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].
وَقَدْ رَوَى هَذَا الْحَدِيثَ ابْنُ لَهِيعَةَ، عَنْ أَبِي الزُّبَيْرِ، عَنْ جَابِرٍ، عَنْ أَبِي قَتَادَةَ، أَنَّهُ رَأَى النَّبِيَّ صلى الله عليه وسلم يَبُولُ مُسْتَقْبِلَ الْقِبْلَةِ . حَدَّثَنَا بِذَلِكَ قُتَيْبَةُ حَدَّثَنَا ابْنُ لَهِيعَةَ . وَحَدِيثُ جَابِرٍ عَنِ النَّبِيِّ صلى الله عليه وسلم أَصَحُّ مِنْ حَدِيثِ ابْنِ لَهِيعَةَ . وَابْنُ لَهِيعَةَ ضَعِيفٌ عِنْدَ أَهْلِ الْحَدِيثِ ضَعَّفَهُ يَحْيَى بْنُ سَعِيدٍ الْقَطَّانُ وَغَيْرُهُ مِنْ قِبَلِ حِفْظِهِ .
