[Machine] The Messenger of Allah ﷺ said, "If his flesh has been eaten, there is no harm in using his urine." Abdullah bin Raja bin Mua'ab bin Sawwar changed his name, and he is actually Sawwar bin Mus'ab. Sawwar bin Mus'ab is considered unreliable. Abu Bakr bin Al-Harith Al-Faqih reported to us about it from Abu Al-Hasan Ad-Daraqutni, the Hafiz. The sheikh and with the weakness of Sawwar bin Mus'ab, there is a difference of opinion about his text. Abdullah bin Raja reported it from him in this way, and Yahya bin Abi Bukair reported it from him with his chain of narration, "There is no harm in the urine of what his flesh has been eaten." Amr bin Al-Husayn reported it from Yahya bin Al-Ala Al-Mutarrif, from Mu'arib bin Dithar, from Jabir bin Abdullah, as a Marfu' narration regarding urine. Amr bin Al-Husayn and Yahya bin Al-Ala are weak, and nothing from that is considered valid.  

قَالَ رَسُولُ اللهِ ﷺ مَا أُكِلَ لَحْمُهُ فَلَا بَأْسَ بِسُؤْرِهِ كَذَا يُسَمِّيهِ عَبْدُ اللهِ بْنُ رَجَاءٍ مُصْعَبَ بْنَ سَوَّارٍ فَقَلَبَ اسْمَهُ وَإِنَّمَا هُوَ سَوَّارُ بْنُ مُصْعَبٍ وَسَوَّارُ بْنُ مُصْعَبٍ مَتْرُوكٌ أَخْبَرَنَا بِهِ أَبُو بَكْرِ بْنُ الْحَارِثِ الْفَقِيهُ عَنْ أَبِي الْحَسَنِ الدَّارَقُطْنِيُّ الْحَافِظُ قَالَ الشَّيْخُ وَمَعَ ضَعْفِ سَوَّارِ بْنِ مُصْعَبٍ اخْتُلِفَ عَلَيْهِ فِي مَتْنِهِ فَرَوَاهُ عَبْدُ اللهِ بْنُ رَجَاءٍ عَنْهُ هَكَذَا وَرَوَاهُ يَحْيَى بْنُ أَبِي بُكَيْرٍ عَنْهُ بِإِسْنَادِهِ لَا بَأْسَ بِبَوْلِ مَا أُكِلَ لَحْمُهُ وَرَوَاهُ عَمْرُو بْنُ الْحُصَيْنِ عَنْ يَحْيَى بْنِ الْعَلَاءِ عَنْ مُطَرِّفٍ عَنْ مُحَارِبِ بْنِ دِثَارٍ عَنْ جَابِرِ بْنِ عَبْدِ اللهِ مَرْفُوعًا فِي الْبَوْلِ وَعَمْرُو بْنُ الْحُصَيْنِ وَيَحْيَى بْنُ الْعَلَاءِ ضَعِيفَانِ وَلَا يَصِحُّ شَيْءٌ مِنْ ذَلِكَ
